I’m Pretty Sure That Leo Might Be A Majority Of Donnie’s Impulse Control

I’m pretty sure that Leo might be a majority of Donnie’s impulse control

Donnie: Now to do some light removing of a thing attached to another thing

Leo: What the- Donnie!

Donnie: It’s fine he regenerates! Remember?

Leo: Uhh No?

It’s been mentioned before that Leo is the one that tends to pull Donnie back when Donnie’s first response to a situation is over the top violence & even in the early episodes Leo tends to be the one that reminds Donnie to be careful with his inventions 

Donnie: I’ll blast it with the boom canons!

Leo: Donnie! Dad’s in that thing!

But other than pulling Donnie back from over the top violence Leo also seems to be the one that tries to question what Donnie’s thought process behind his inventions were

Donnie: Sheldon needs time to recharge before firing his anti- turtle ray

Leo: Why is that a ray Donnie!?

Similarly to how Leo is the one that typically pulls Donnie back from responding with violence as a first instinct, Leo also seems to question why Donnie would make certain inventions such as when he questioned why Donnie grew a giant pumpkin in the script for the scrapped season 2 episode Gourd Almighty or when when he asked why Donnie built an anti- turtle ray in the 360 Rooftop Laser Battle video.

Leo: Donnie these are amazing, and I know everything I say sounds sarcastic but I’m being completely genuine 

It’s shown that Leo does genuinely enjoy seeing the things that Donnie builds so the fact that Leo sometimes questions why Donnie would build certain things could be another example of Leo pulling Donnie back from going overboard with his experiments.

Similarly to most scientists Donnie most likely would rather see whether he could build something rather than think about whether he should build something, which is probably why Leo sometimes steps in & asks for the reasoning behind certain inventions
