As much as I’m now noticing how people dislike Sasha for being mean to Rhys, I haven’t seen anyone mention the fact that Sasha stopped to retrieve Vaughn before going after her sister at the end of the death race.
I mean, the last we see of Vaughn in the race is when he was driving the truck that is involved in the wreck that can determinantly kill Fiona if you don’t ditch fast enough. The next time we see them, Sasha’s on the bike she whacked the psycho off in the arena, and she’s got Vaughn behind her. Even if she only went to the wreck to get her sister, she stayed long enough to let Vaughn come with her. Such heartlessness.
