During this mission (for those who haven't played) the object is to get one of four people to stand in front of the Giant Dinosaur and where Boone's beret. Whoever is standing next to you will get shot.
For this mission I suspected Manny Vargas as he definitely did not like Boone's girlfriend. After getting Manny killed I went back to see Boone who referred to Manny as female.
I'm very certain Manny is male! As a result I don't really know if I make the right choice or not! Also a couple of Novac Settlers have learnt how to levitate when sitting outside!

Thats a script bug allright. (Manny is not guilty btw )

huh. I was pretty sure manny was male too...

just kidding.... well, I'm not, he isn't a girl, but, whatever. you know what I mean. did Boone agree to accompany you, as if you had picked the right person?
