Zac looks at Cassie for a few moments, somewhat surprised. Sure, he wasn't unused to making friends, hell, he always went out of his way to do so, but being referred to as someone's friend first, instead of the other way around, as was the normal for him, was a nice surprise. Grinning, he wraps his arm around Cassie's shoulders and pulls her close, grinning like a madman. "You got that right, Cassie! Friends to the end, right?!" he says rather loudly, followed by an equally loud laugh.
