Something about what Bucky just said must have been the magic word, since it gets Inigo to stop flailing around in the water as if he's drowning in a place where his feet can clearly touch the bottom and instead just stay still at the spot he's at now.

His jaw is dropping again though - thankfully not into the water this time, but still. He looks offended.

"Do you really think I'm not capable of relaxing?" Bucky would be 100% right about that fact, mind you. Despite the dramatic offense on Inigo's face. "I can relax! Whenever I want to!"
