But at the end of Guardians Of The Galaxy, Yondu revealed that they never actually delivered Quill to his father as per their contract, meaning that Yondu and The Ravagers actually raised him.
Of course, since Guardians Of The Galaxy Vol. 2 will see Quill finally being introduced to his father Ego, played by Kurt Russell, all kinds of different emotions are set to bubble to the surface for Yondu.
This is complicated even further by the fact that Yondu and The Ravagers were the ones who actually abducted Peter Quill from Earth all the way back in 1988.
Plus, I imagine Ego will have some rather choice words for him, too.
