I have a feeling that Peter had a lot of nightmares after, you know, being abducted by aliens. And I think everyone who’s ever seen Wrath of Khan has worried about brain eating space bugs at one time or another–if I lived in space after being kidnapped by actual aliens, I’m pretty sure that those worries would intensify. The galaxy’s a big place–what if they’re really out there? Yondu seems like the type to confidently dismiss Peter’s little kid fears…but then worry about them himself. Kraglin appears at the very end of this comic–he seems like the type to sleep through anything.
