Okay but who between Sid and Sullivan kisses the other when they're rambling and just look completely and utterly adorable? And would it be their first kiss?
HOOOOO BOY ok I’ve been thinking about this for houuursss
Sid definitely kisses Sullivan when he’s rambling. Sullivan sometimes (often) has trouble leaving his work, well, at work. He’s always thinking about something to do with a case, always turning something over in his head, trying to piece things together. If it’s not work it’ll be something personally he’s fussing over (so on more than one occasion definitely his feelings for Sid) and his brain very rarely seems to rest.
So he’s a rambler of the highest order. Either to himself, under his breath, or out loud to whoever’s listening, most likely Sid. He likes to ramble while pacing round the room, twiddling with something in his hands, or fixing tiny little imperfections - specks of dirt on his desk etc.
When he does it around Sid, Sid often lets him go on for a few minutes, just to help him get his ideas out of his head. Then he notices that the rambling is starting to become more like unhealthy obsessing, and Sullivan needs to step back, relax, and let himself rest. (He needs to stop holding himself to such ridiculously high standards, most likely put in his head by his father, but Sid has thoughts on that man that he has to swallow down often).
To get him to calm down, Sid will often have to hold Sullivan physically still - either by taking his hands to stop him fiddling, or by holding his waist or cupping his jaw. Then he’ll kiss him softly and gently until he can actually feel the anxious tension releasing from Sullivan’s muscles underneath his hands.
Their first kiss probably happened a lot like that too, with Sullivan nervously trying to explain how much he actually likes Sid and how he knows he shouldn’t and he doesn’t know why he’s so drawn to him but all he can think about is kissing him but he’s never brave enough to and this is so embarrassing Sid can’t possibly return his feelings and— oh.
(Sid did of course return the feelings, and let Sullivan know this by kissing the living daylights out of him until both of them were extremely dizzy and in need of a cup of tea)
Thank you so much for asking my sweet I loveeee getting to ramble about my hcs so I hope you like this!! 💚
