Ailín Salas (Roberta)

So, the actress who played Alex's female friend in the film was only 14 (if the internet is correct with her birth year being 1993)? I know she was not shown nude in the film, but she was in the shower with Alex at one point. Did anyone (viewers or critics) point out that particular scene.

Please save all of the "you did not get the point of the film or that scene" because I did. I am intentionally going in a tangent on this aspect.
