This one might be a stretch, but we're betting there was some planning between these lines. As we've learned, Yondu raised Peter after taking him from Earth. He taught Peter all kinds of useful, civilized Ravager skills, like how to steal and fight, and basically set him up to be the capable, badass Star-Lord we see in the movies.
But what exactly were those two getting up to for all those years? If you said "robbing a bank on A'askavarii," buddy, you have way too much time on your hands. But then again, so do we. Pleasure to meet you. Anyway, if you recall in the first Guardians, Peter Quill stops Drax from killing Gamora in the prison by showing off his scars, one of which came from a Kree girl who caught him with an A'askavarian he had to seduce for a job. Huh, you said thoughtfully. Huh.
So then, in Guardians 2, Rocket, Groot, and Yondu jet down to Ego's surface in a little mining ship, which Rocket calls "an old piece of equipment Yondu used to slice open the bank of A'askavarii." Huh, you scream at your computer. Huh. Could…could both of those stories be referencing the same job? Considering how much James Gunn loves to throw exactly that kind of ridiculously insignificant detail into his films, we're saying there's a pretty good chance. That's all we're saying. We're also saying, if James Gunn ever wants to make a Guardians prequel about The Space Adventures of Yondu and Pete, we'll be first in line.
