Hazel knew that Annabeth had meant to keep the team together when she started the whole new 'Fatal Flaw' thing. The deal was that everyone had to find out their Fatal Flaws and tell them to their teammates so that they could all understand each other better. But even though, Hazel had trouble finding her Fatal Flaw, although she knew deep down she had one. Everyone does. She just needed sometime to think about it, and now was the time.

Nico had told her that his other sister Bianca had said something about the Fatal Flaw of the children on the Underworld being holding grudges, and for a while, she considered that. She might have settled on that idea if it wasn't for Frank and Percy. Back when she still couldn't control her powers well enough, whenever a gold nugget or any mineral popped out of the floor, she was afraid she'd hurt someone who used it. This got her thinking back about her old life in the 1940's, how she never let anyone use her resource no matter how much she hated them because she didn't want them hurt. Hazel didn't hold grudges. Infact quite the opposite, she forgave. She forgave her mother even though it was too late, and she had doomed her, she forgave the kids at her school for bullying her and never gave in to them, gods, she even forgave her own Father (well, a little anyway) for not looking at her or offering help until it was a no-going back point. No, Hazel didn't hold grudges.

Hazel wondered what her Fatal Flaw truly was. So she went back into all her deeds to find her week spot. Back in New Orleans, she'd done nothing quite that strange, well expect popping jewels straight from the floor. Then, she'd moved to Alaska, where she'd made her mistake of listening to Gaea's voice and almost reviving a gaint. That was one of the biggest mistakes that she'd even made in her life. And then... there was death. Hazel and her mother had died and were both harshly sent to Asphodel where Hazel suffered because of her memories. That was where Nico found her and brought her back, and she was still grateful for that. She had stayed at Camp-Jupiter for a few months with her new best-friend Frank, and they'd went on that great quest when Percy showed up.

Hold on... something triggered in Hazel when she thought about that. During their quest, Hazel did sense her Fatal Flaw.

She was absolutley definitely scared. No, not of the fact that they have lesser than a week or they'd doom the camp, but of messing up all over again.

That's it! Hazel thought. That was her Fatal Flaw.

Through out the entire quest, Percy, Frank, and she had been going into life threatning situations and all she had kept in mind during most of them was how she might do something wrong, just like she'd done in her old life. She'd ended up killing the most person she cared about against the odds: Her mom. She was afraid of dooming Percy and Frank too. That was her Fatal Flaw. Fear. Hazel was afraid she'd do something wrong all over again and doom her friends and blow up all their hard work.

Fear. Even newely introduced to it, Hazel knew fear was her foe now. The part of her that faulted her and made her chose wrong choice. Fear. It was her death-flaw.
