In the novel It’s described that the space was too dark to see clearly. Isaac knew who Felix was but Felix could not see isaacs face.
In more flashbacks from the sex scene (taking this from the spanish translation), Felix says he wishes he could see isaacs face.
Oh i understand know felix doesn't know he was sex with isaac. O feel bad for isaac a little :(
