In Riddick, we get to see something of a "lust triangle" between Santana, Dahl, and Riddick. Now, Dahl, when in dialogue with Santana, states that she doesn't "fuck guys". She is subsequently referred to as a lesbo. Santana is shown pretty early on to be someone who likes (and abuses) his women. There are quite a few scenes that build on their relationship (or lack thereof).
But how about Riddick? He pervs on Dahl when she's in the shower (a scene which does also serve the purpose of showing how Riddick got a hold of a mirror). Later when he is chained up inside the station, he states the following:
Then when it's all over and the rest of you are ready for Dead Animal Pickup I'm gonna go balls deep into Dahl. But only because she asked me to. Sweet-like.
Then there's this scene:
Riddick: You grant any last wishes? I was referring to you [Dahl].
Dahl: Not that the chains aren't a hot look, but no. I'm not gonna straddle you in front of all these guys.
Riddick: What if I killed all of 'em first?
Dahl: Easy, boy. There's a lot more tranq where that came from.
Riddick: Tell me what you see outside that window, Dahl.
Finally, in the climax where Dahl rescues Riddick, she is shown to be straddling him as they are lifted back into the ship. She then says:
Let me ask you somethin', sweet-like...
… and a little later on, Riddick tells Johns:
Tell Dahl to keep it warm for me.
Was our hero supposedly sex-starved after his time on the planet? Or was he simply trying to get under her skin? Considering the above dialogue, does that mean that Riddick had sex with Dahl and essentially turned a lesbian?
(FWIW, I watched the Director's Cut.)
