Kazen lowered his keyblade and dispersed it. He kept his sword readied though, looking onward as Soren explained what had happened. He just shrugged and sighed. 
"You just can't seem to keep in one place, now can you?" he joked.
Once Soren had finished his explanation he nodded at the suit and approached it, he tapped it with his knuckle and grinned. 
"I like it, but it needs a new paint job." he then turned and went to exit the lab. Kazen turned to Soren and looked him in the eyes, taking in his new appearance and once he'd confirmed that this was indeed his old friend he placed a hand on his shoulder and grinned. 
"There's a lot to do, but it's good to have you here with me. I'll beat you in swordplay some time soon though, don't worry." He sheathed his sword and went on his way. 
"Come on, there's work to be done and I can't leave Cid hanging much longer. It's good to have you back though." With that said he strolled out of the lab and back towards the lift. He needed to meet up with Cid soon so they could run the final stages of the stadium before the opening tournament next week.
