Colin couldn't help but smile at Zach's answer to the question. "It was a bit off, yeah?" He took a few steps forward, taking a brief moment to stare at him in the eyes. He would know it was him for certain this way. He let himself watch for a moment before his smile widened. "It is you!"
He turned Hector around so he was resting against his back instead before moving to wrap his arms around him. "How are you? Are you all right?" He looked him over curiously, eyes focusing to catch any injuries. He was used to doing this with Dennis. There didn't appear to be any injuries. He let himself stay close, not particularly concerned with personal space. People usually stepped away if it was an issue.
He smiled up at him a little. "Man, what Jus-" he cut himself off. "What our mutual friend would have to say about this meeting. I'll have to tell him. You won't say anything to anyone about seeing me, will you?" His brow furrowed. "I have to take care of Den, and I can't do that...if I'm not out here..." And not in Azkaban.
