A/N: prompt "went to a con/party as a couple"

Having Robert as a flat mate came with pros. This is not one of them.

Ned should've said no. He could've said no. But he took it himself long ago to keep Robert out of trouble – so when Robert knocked on his door and promptly dumped an orange shirt, a pair of khaki shorts and a beaded necklace, he just sighed and put the outfit on. Although he drew the line at the green contact lenses.

Their Office is holding a costume party and Ned already knows which one they're going to be. Robert as Poseidon and Ned as Percy Jackson. He's a big nerd like that.

When they arrived, they immediately spotted Cersei, dressed as Athena, complete with shield, cloak and sword, and Catelyn, dressed in a shirt similar with his and a blonde wig upon her head. His heart leapt to his throat. She came as Annabeth Chase. Robert literally swept Cersei away and left them alone, standing awkwardly.

"So, I'll just leave.." he started to say the same time Catelyn spoke, "Would you like to get something to drink?"

They laughed at the same time and he thought that her laugh sounds like music to his ears.

Later, after several glasses of wine, he would tell her that he liked it better when her hair is auburn and see her blue (blue as the river, blue as the summer skies), blue eyes soften.

(The next morning, he would blame the alcohol for making him confess something like that to his biggest crush.)
