So sorry this took so long! I’ve been snowed under with work and uni- but I hope you like it!
Sid x Sullivan Relationship Headcanons:
•first of all, aside from the odd little look back (like the gif above) these two are absolute pros at keeping their relationship hidden.
•that’s not to say that they haven’t slipped up though- they have accidentally worn each other’s clothes occasionally and often swap wrist watches.
•they have adorable dates. Sid will loiter around the back garden gate of the Inspectors house and they pretend that it’s about some ‘informal questioning’ when Sullivan lets Sid in.
•it’s actually just an opportunity to have dinner together. Sullivan is a surprisingly good cook and he loves the chance to show off for Sid.
•they’ll sometimes dance around the parlour together, Sid leads and holds the Inspector tight in his arms.
•when they bump into each other around Kembleford they keep up their grumpy act towards one another, but if you look really closely you can see smiles threatening to break through their stony facades.
•Father Brown 100% knows about the relationship and he is very discreet. He wants Sid to be happy and he’s glad that the two men have found one another.
•when the Inspector has a few days off Sid will mysteriously vanish. No one ever puts two and two together, aside from Father Brown, and the men often go to a deserted seaside cottage to be alone together.
•Sid is a stargazer and teaches Sullivan the names of all the stars.
•when one sees the other in uniform (Sids Chauffeur uniform or Sullivan’s formal Police attire) there’s so much teasing and unresolved sexual tension. It’s super cute.
•there’s almost a fire when Sid tries to cook for Sullivan for their anniversary, so they agree that it’s best if the cooking is left to Sullivan.
•they’re incredibly happy together.
