I feel like Damian had a phase where he became obsessed with the Paddington movies like 6 months into moving to wayne Manor, and for like maybe a week he tried the nice and polite thing. Only issue is, everyone is now on edge every time he's considerate.
Dami: Drake, I have made you a sandwich.
Tim, whos just gotten back from a two week titan's mission and is now highly suspicious: What's in it?
Dami, exasperated: Marmalade.
Tim, even more confused: Why?
Dami, just staring into his soul expectantly, trying his darndest to smile politely:
Tim, too tired to deal with this, taking the plate:
Damian runs off, Tim gives up.
Safe to say, after a week of everyone still being on edge he gives up and gains a new interest in warrior cats or smth.
