"Embrace your criminal destiny, kid!"

I Trust You

Kind of! At least that’s what Timmy would like to think. Personally, I don’t see Dev as the type to be very open with others (Hazel being the exception). I imagine Dev just acting like he always does, not fully understanding why Timmy wants to spend time with him. Maybe one day when Dev grows up, he’ll realize it and wish he had appreciated it more back then.

As for Peri, I think it’s a mix of both. We’ve already seen how nervous he was with his parents before being reunited with them, so I imagine it would play out in similar way with Timmy 🤔 I remember someone from the FOPANW crew mentioned something that Peri is the type who wants to stand out more than his parents. He’s probably aware that Timmy doesn’t remember him. And because of that I can see Peri trying his best to appear classy and sophisticated because he wants to leave a strong first impression on Timmy just like what he did with Dev.

I like to think that he did! Though when it comes to Timmy calling him out for being a terrible father, I can think of four possible possibilities from worst to best outcome:

1) Dale straight up doesn't care as he sees Dev just as an "asset" to him and absolutely doesn't see anything wrong with that. ( I can see this outcome especially if the Dev clone theory is true ) That or he would always change the subject every time Timmy tries to bring out that problem.

2) Dale would tell Timmy that he didn't actually neglect Dev and did spend his time with him when he's less busy ( which is a lie and Timmy can obviously see that ) He probably would come up with more excuses like he already gives his son devices that give him everything he wants, which should be enough to take care of him for Dale.

Though I also can imagine him asking Timmy if he can take care of Dev while he's doing his own thing, which I guess is better than Dale asking Timmy if he wants Dale to hire a human babysitter for his son instead since the Au Pairs isn't good enough to provide care for Dev apparently.

3) Dale took Timmy's words about him being neglectful to his son and promised Timmy that he would try to fix that and be a better father......as long as Timmy is around them.

This causes Dale's relationship with Dev to be rather shallow than genuine, as clearly he's only doing this because of Timmy. Perhaps it would take a while until Dev realizes that as well and breaks his heart further.

4) Dale took Timmy's words to heart and ACTUALLY becomes a better father to Dev holyshit (delusional)

Either way, I can see Timmy being rightfully frustrated with how Dale treats his own son but can't really do much about it due to some reasons, like maybe it could jeopardize his career or maybe he couldn't see a positive outcome for that. He probably would bring Dev out with him sometimes when he could, and try to give him a childhood he couldn't have with his own dad.

Headcanon: Deep down they both want to be their fairy godparent/godkid again after losing them, but don't believe they deserve each other and feel like they aren't worthy to be their companion anymore
