@iatheia replied to your post “Leonard and Mick in Doomworld”
But the “good boy” and the dog comment, tho?
Well, that’s how the conversation went:
Leonard: Nice work, Mick! Now hand it over.
Ray: Mick, no! You already gave it to him once. You know what happened.
Damien: That was Thawne. This time will be different, big boy.
Jax: Don't do this, Mick.
Amaya: Mick, I don't care what anyone else thinks. I still believe in you.
Leonard: Enough! Mick, hand it over. Like a good boy.
Mick: You mean a good dog. That's all I am to you. An attack dog.
Leonard: Now, that's not true. Sure, we both know you're not the sharpest tool in the shed, but that's why we're partners. Remember?
Mick: You're right. I'm not a genius. [he throws the spear back at Amaya] But I'm no one's dog, Leonard. Not anymore.
Leonard: Well. I guess you can teach an old dog new tricks.
Mick: Undo this mess.
The “good boy” comment came after Amaya’s “I still believe in you”. That’s what I meant when I said Leonard had a big jealousy-induced stupidity moment.
Amaya opened herself up to Mick. These last two episodes (or rather since the season started), Mick’s problem was that he didn’t feel like he belonged anywhere. The legends don’t trust him, Len put a tracker on him (I assume Sara and Amaya told him), and both sides underestimate him - they treat him like an idiot and a brute that has to be controlled (in Len’s case, he doesn’t know about the years Mick spent as Chronos or his time with the legends, he’s operating based on the outdated original terms of their partnership: Len’s the brain and Mick the muscles). So, to hear that there was somebody that believed in him, despite everything that happened (despite the fact he betrayed her last episode by siding with the Legion), Mick needed that.
And I think Leonard, who knew Mick more than anyone, can see that she genuinely touched him. It’s at this point that he gets impatient (“Enough!”), and demands again that Mick hand over the spear. Mick just gives him a stubborn look like “really?”. The thing is, Len can’t really one-up Amaya here, this version of him isn’t capable of admitting to seeing Mick as a friend and not just his partner (his muscle), or of having the sort of faith in him that Amaya does (Len isn’t capable of just having faith in people). So he can see he’s losing Mick by the look on his face, he gets jealous and annoyed and drops that “like a good boy”, which I think is some sort of stupid attempt on his part at reestablishing the status quo, to remind Mick of how they work (that he’s supposed to listen to him not anyone else), ask him to stop thinking and do what Leonard says because he’s more intelligent than him and knows what’s best for them. He doesn’t like having to compete for Mick’s loyalty (or anyone’s affection).
As for the dog comment, he denies that that’s how he sees Mick at first, in answer to Mick’s accusation. And I think that’s true? Like in his head they have an equal relationship where Len does all the thinking because he’s the genius one. He only calls him a dog after Mick throws the spear at Amaya, betraying him for the second time in like 2 days? So he’s just lashing out.
(It’s kinda like when Mick called him a punk kid or whatever in S1, they’re not always nice to each other.)
