Honestly, Finn's pretty happy to see Blue's abilities coming back to him, even just temporarily or sporadically. The frustration he can feel from the Mu is... understandable, so it shouldn't be all that surprising to see some cutlery gently floating around in the mess and Blue by himself.

He, uh- He makes his way over, gently picking the sharper objects out of the air as he goes.

"Hey." Just a casual greeting for now as Finn approaches, not wanting to startle him or anything.
