I particularly like how Dum Dum's isn't huge and big but comparative to their size that beetle is STRONG.

Thanks! I'm rather fond of Dru myself. I don't do enough insects for daemons. Too many birds, way too many weasels, and not even insects.

I can totally picture Haddie with James D'Arcy. They'd shoot each other plaintive glances whenever Tony acts up.

My mental image for Jarvis is sort of him doing something and suddenly reaching out and grabbing Tony without looking and preventing him from doing something dangerous, while continuing to do the thing he's doing uninterrupted.

Jarvis: I told you not to touch that, Master Tony.
Tony: You aren't even looking.
Jarvis: I don't need to look. I know you.
