Cat landed softly on the roof. Her practiced maneuvers had done her well. She was able to slip into the store that was practically a fortress, steal what was surely a priceless amount of jewels and diamonds, and rappel our without being seen.

She grinned to herself as she lowered her haul. This was her best raid yet! Any other raids like this one were typically stopped by her new boyfriend, but since Peter was still sleeping and thought she was there with him, she was able to do this without being caught.

She felt bad about betraying his trust and leaving, but this bounty was too much to give up! Besides, she though he would never find out about it.

She thought.

"And just what do you think you're doing?" A sharp voice said from behind her.

She turned, seeing the masked hero fully dressed and standing before her. She wasn't worried that she left or he was here, she already had the loot.

It was that he sounded... disappointed. Admittedly, it almost made her sad.

Almost.

"You leave in the middle of the night... to come steal? I thought we were through this. I won't let you." He said, clenching his fists. He wouldn't severely hurt her, but he didn't intend to let her get away.

"Honey, I love you, but come on, you knew this would happen eventually! Besides, I have the loot already... how bout we let this one go and call it a night, hm?" She said. He stayed silent.

"Come on, I'll drop off the loot, we will go back to bed, and we will finish off the nights strong, hm? This is my biggest haul yet, at least let me-" She said, but was cut off when the webs shot from his wrist, yanking the bag into his hands, and then behind him.

"We will go home all right, but not with the bags. It's not yours Felicia." He said to her, holding his ground.

"Alright... I see where this is going. No choice is there?" She said, taking her stance. "For old times sake?"

"Those days were fun, so why not?" He replied, taking his stance as well. The two charged, him leaping and webbing her feet, before landing and attempting to restrain her fully.

But before he could reach her, she threw a rope with strong magnetic balls on the ends of them. Snapping him up right and making him fall. She cut the webs quickly with her claws, grabbed the bag and ran before he could even get up.

She kept running and leaping rooftops until she got to Oscorp. Not the best place to hide, but she was exhausted and didn't think he would find her there. She had to switch hiding places, since her last one got her bitten by this red and blue spider. She hated the thing, squished it, then left.

She sat down for awhile, waiting to see if she would be found. When she wasn't found by the second hour, she got comfortable and decided to go through her bag and find the best stuff.

It really was a good haul. She found a pearl necklace she really liked and decided to keep for herself. She knew Peter would be none too pleased with the new trinket, but she liked it.

She didn't before, but she started thinking of how this would... complicate things. He had placed trust in her. Now she betrayed it. This was who she was... but was it worth it?

She began fidgeting with one of the pearls around her neck when the voice came again from behind.

"You think I wouldn't eventually find you?" He said. She laughed, that would teach her to let her guard down.

"You never quit, do you?" She said, still chuckling as she stood up.

"Alright Spider, lets-" She said, but was cut off by a pounding in her skull. Something wasn't right.

"Hey, are you okay?" The hero asked, walking up to her, removing his glove and placing it on her head. He set his lips in a hard line.

"Cat, you're roasting. You've got a heavy fever. What happened?" He asked. She shook her head, suddenly feeling like crap.

That's when he saw it.

Two small dots on her skin, just above her collarbone.

His stomach took a dive. This was Oscorp, and she had a spider bite.

Not good.

He taped a note to the loot bag, and took off, taking Felicia back to his apartment. She was disappointed on the way back that her plan didn't work, but there was a silver lining.

He let her keep the necklace.

When they got back, he stripped her costume off down to her underwear and laid her under the blanket, staying up with her, constantly applying water to a cloth on her head, trying to control her temperature.

She eventually fell asleep, as he stroked her hair and spoke softly.

"You'll be alright. Tomorrow morning, you'll..." He said, but she passed out before she could hear the rest.

When she woke, she felt...

Great. Fantastic, actually. Like she was completely rebuilt overnight. She smiled and got up, feeling stronger than ever! She was glad whatever got her last night was done. It was probably exhaustion in her opinion. She worked hard while fleeing.

She got dressed and was feeling enthusiastic when Peter walked in from the bathroom. His face didn't look happy. He looked worried, almost concerned.

"Hey! I'm better! No need to be upset anymore!" She said, giving him a kiss he only half heartedly returned.

"It's because you're better already that I'm worried about." He said, his tone a shade grim.

"Was it that fun taking care of me? I should get sick more often." She replied, sitting on the bed. He didn't say anything. He walked over and began taking her shirt off.

"Morning sex? Okay, I'm down with that." She said, feeling frisky all of sudden. His expression remained grim and stripped to her underwear again. She leaned up to makeout with him, but he caught her jaw and turned her towards the full body mirror.

"Look at yourself. Notice anything?" He asked quietly, watching intently.

She didn't at first, but then she saw her belly.

She wasn't fat.

She hasn't lost any of her curves.

She was ripped.

Not rock hard, but ripped. A full six pack lined her torso. Her hips were soft looking and her body was full, but harder and felt stronger. She flexed her arm and saw the size of her bicep. It was twice as large as before.

She didn't know what it meant, and didn't know what it came from, but she had changed drastically overnight.

"Two middle fingers down, the other three out. Aim the inside of your wrist at the mirror." He said quietly, face having gone pale.

She did as she was told, and the craziest thing happened.

A web shot out of her wrist and hit the mirror.
