The word “fight” can be interpreted a number of ways, so you get one drawing of the two of them doing some friendly sparring and one where they’re just having a stupid sibling fight
Does Donnie ever come across some of Timothy’s old drawings of his rescue plan later on?
Tim flat out shows him! He’s pretty shameless about the whole thing, and thinks it’s hilarious how insane the idea was (a kid taking on Baron Draxum). But Donnie (even still) doesn’t know how to handle the idea of someone willing to sacrifice their own safety for him.
always happy about the fact that in 2012, mikey often asked donnie questions if he didn't understand something and donnie always answered no matter what
this can be seen in a bunch of episodes but my favorite example of it it's the one in half shell heroes where mikey is extremely excited to be in the museums and is the one actively asking donnie questions about the exhibits they saw and also actively listening to donnie's explanation (before raph got silly lmao). he was very excited to learn!!!
And while it's true that mikey would lose interest quite fast if the explanation got too lengthy with too many technical terms, it doesn't change the fact that he does retain the info donnie is always rambling on about different things!!! (even if mikey himself doesn't notice he's doing it lol) and also i find it very sweet that no matter if donnie himself got annoyed, donnie would always answer the questions. no matter what. he would always try to explain if he didn't understand something
This is prob because mikey is the one brother who is often seeking out donnie to pass time around him Meaning that donnie might have used mikey as his rubber ducky whenever mikey hangs out with him while he's working (explained him a lot of his experiments and theories while trying to solve them himself and in this way mikey also learnt in the process WHILE spending time with his brother! win win!)
it also helps donnie because accompanies him while not letting him get lonely in his lab 24/7, sometimes explaining things to someone makes it better to understand it yourself AND it's shown in the comics that donnie is quite used to his brothers just Living as background noise and literally cannot function without it lmao
They are literally the two smart kids in the family even if none of them notice it and it's all because mikey looks up to his brother and is like an sponge with donnie around. donnie is actively teaching mikey and mikey is learning! even if they have no idea they are doing it
I'm currently de-compressing after a mission in my lab, which means spinning in my chair, watching Jupiter Jim & listen to my favourite song on repeat.
