Alex had a choice. Be an ass to her or do something that could help her and maybe other people too...
"Maybe... I can teach you?" He was once like that, didn't have a clue how to cook. But necessity took over and while there were no other staff through trial and error Sean and himself had learned how to cook with the few cookbooks they had at Charles'. Though this had changed when they'd moved out, Alex had got a few more after it had changed from something they needed to know how to do to something he enjoyed.
He'd stood with Sean like this plenty of times at their refrigerator, trying to cool New York City they'd joked as they debated what they were going to eat that evening. And there were the stolen kisses that no one else saw. Of course there were plenty of times it had ended in them walking to get pizza. But that wasn't an option then.
He reached into the fridge to see what was in there, then moved to poke through the cupboards to see what he could make. He made a note to come back when he couldn't sleep and make something else. Proper cakes that didn't involve randomly being cursed. Maybe even leave a pie or two for people. Let his bouts of insomnia brought on by his PTSD be useful.
