Nebula's role

Ayesha offers Nebula as payment for defeating The Abilisk. However, according to Feige, the villainess will work with Taserface through most of the movie (in order to get a new hand). And this does make me wonder whether she will be a true Guardian of the Galaxy or she'll end up betraying the team in this or the next movie.

According to actress Karen Gillan, we'll find out more about Nebula's backstory in Guardians of the Galaxy: Vol. 2. The audiences will be able to empathize with her character, since the movie will explain what her motivations are and how it was to live with Thanos as her father. Does this mean that we will see yet another cameo by the Mad Titan? James Gunn said that Thanos wouldn't appear in this one, but maybe this will be yet another surprise from the director.

We can expect that Nebula and Gamora’s relationship and rivalry will be explained further during Guardians of the Galaxy: Vol. 2. In the first movie, Karen Gillan's character also betrayed Thanos, so there is common ground between the sisters.
