Okay so I saw your second message saying you couldn't read my reply, so I'm posting it here again. I should've thought of that, the app won't let me see stuff on my message board either, only my laptop does. But maybe it's different for you, idk! Anyhow, here's what I said:
Hm, how about something from their school time? Like, fifth or sixth grade, and maybe Dean wants to draw something but has been lacking inspiration and so he talks Seamus into letting him draw Sea and they end up kissing for the first time or something? Idk, this might be crap, but it's the only thing I can come up with right now. (:
hope this helps!! xx
