Gina Rodriguez: Anya Thorensen
[the team kill an alligator & examine it's mouth]
Lena : Lena: Whoa. It's exactly the same as the flowers. Look at the teeth. Concentric rows. Something here is making giant waves in the gene pool.
[the paramedic, Anya, holds the alligator's mouth open. She has no tattoo on her arm]
Cass Sheppard : Sharks have teeth like that, don't they?
Dr Ventress : Do you think it's a crossbreed?
Lena : You can't crossbreed between different species.
Anya Thorensen : Lena, this is getting heavy.
[Later in the movie, Anya has acquired the tattoo]
