Kraglin and Nebula

Kragula is the fan-dubbed relationship pairing between Kraglin Obfonteri and Nebula, a daughter of Thanos. Several fans ship itbecause of a small scene exchanged between Nebula and Kraglin, where nebula reveals her tragic past to the latter of the two.

The Mutiny of Yondu Udonta
After both of them are alone, Kraglin shows Nebula their artificial arms and offers her to find another one if that artifact doesn't work out. Instead, she claims that this one will be fine. As he escorts her to the ship, Kraglin asks what she wants  with her share. Nebula shares her history with Kraglin, and tells him she wishes to kill her sister and father so they'll know the meaning of pain. Kraglin, obviously upset by her statement, says he thought she would buy a pretty necklace or a nice hat before he wishes her good luck.

They do not have any form of contact for the rest of the film.
