Noctis wouldn't call it trepidation, exactly. More like...disgruntlement. What's Angeal so invested for, anyway? Why's he so intent on horning in on their private, personal thing that's supposed to be just for them?

Noctis never did come around to enjoying never having a lick of real privacy his whole life.

So he's a bit grumpy, but he's here, because Prompto wants to do this. He's sat himself down on the ground with his back leaning against the outer wall of the prison - because that's the building Angeal wanted to meet them at, and Noctis decides to just neglect to mention why this building is here in the first place.

"Speak for yourself. He oversteps, I've got a fist with his name on it right here." He's...probably joking. Or exaggerating. Probably.
