Inigo ever feeling confident about anything in general may be a little bit too much to ask for..

But he's going to try all the same. No matter how much he may be whining right now, he does trust both of them. At the very least he is absolutely certain they wouldn't leave him to drown, so that means there's no real risk here, is there?

"I.. It's okay."

His voice still shakes a bit, but he steadies himself.

"I'll let go myself." Because it just feels a lot less scary that way. Taking action, rather than waiting for the inevitable. (He is closing his eyes again for the moment though, sue him.)

So Inigo sucks in a breath, and then pulls his arms away from both of them. He's still kicking underwater, and though for a moment it goes slightly faster, threatening to turn into panicked trashing, he manages to control himself at the last moment to keep it steady instead.

".. It's.. It's working, isn't it?"

Of course he could just open his eyes and check it for himself (not to mention that he'd kind of be feeling it if he was drowning right now!!), but apparently he wants to hear it from them instead. Like his own opinion and senses aren't enough for him to believe it.
