I'm not too sure, so i'm reserving judgement...
One of Ethan's goons has name (Julian or something) the other doesn't yet...
Erynn doesn't acknowledge them and says she hasn't seen Zane in a long while, so i don't think "non-Julian" is Zane.
My main suspect of being Zane is the surfer dude who flirts with Nikki during her last visit, Brooke has said her brother likes to surf... it immediately rang a bell for me.

This dude right here.
Since we have a beach date with Erynn scheduled, our first meeting with him may be just around the corner.
