"...Oh shit."

That's the most profound thing someone can say about this place. Yondu follows him in, looking at the monitors, the chair, the thick cables.

It's not his world, but what kind of set up this is immediately evident. He's seen it before. Lived another version of it. He won't ask for the explanation, he'll wait for it to be given. Or he'll trash the shit out of this place. Whichever it is that his buddy needs.
