That look was a bit more like the usual Tracey but he wasn't relieved. "You don't know when he's coming back...he's left...Who does that?" He wasn't exceptionally close to Theo but he hadn't expected this. Even if he would have liked the guy out of this situation it was clearly bothering Tracey. He didn't like to see that. He had already gone through her being upset over Theo once. In Zach' mind, the guy wasn't worth it.
"Okay." He said, reaching out and putting a hand on her shoulder. "It's going to be okay Tracey."
