Sirius started into Teddys face, a strange aching feeling rising in his chest. They were so close, all he had to do was lean in a little and they'd be kissing...
Nonononononoooo This is Remus' son he is your cousin even if he's removed and did you not even listen to Peter you don't love him you just want his approval so stop this stop it stop it he's your friend and if you kiss him you will fuck it all up he has already told you he has a girlfriend stop stop stop STOP
Sirius took a shuddering breath that would hopefully just be mistaken for leftover sadness and not full blown panic. He couldn't help himself completely though, and pressed a kiss to Teddys hair. Like he'd do for Remus or James. Totally normal friend stuff.
"Yeah. Okay. We can both wallow tonight, and tomorrow we'll be pur brilliant, vivacious selves."
