It's not a crime to admit you have it wrong... happens to every single one of us.Dating is not a relship, I mean how many exes you have then,
The serious was set up by Ethan, Zanes tells that on the beach, I guess it was with Cara I'm now too lazy to fire up that game and look for it sorry besides, that only aplies when you are on Erynn path.
I tried to find it in the WT but that is horrible better to search in my saves and show it.
And Cara doesn't even go to the beach, with Cara we go to the park (were Iris is relaxing topless).
Surfer dude(who i belive is Zane but have no actual solid proof) only on screen appearance is on the Nikki path. And he comes and goes without saying anything relevant.
There's a lot of talking about him, but not much from him(yet).
