Ianto kept a firm grip on the other man's hand as they fell through the air, trying to keep himself feet-down as well, not caring if maybe Sulu might be squeezing his hand tighter than was really at all comfortable. They were free-falling through the air, and he knew that this was probably one of the other man's biggest fears, the least he could do was suffer a bit of discomfort in support of the other man, after all.

As they hit the water, Ianto felt himself wrenched away from Sulu as he hit the water at a bit of a different angle than the other man and shot off to the side a little on a diagonal. Luckily, the water was clear, and he didn't go down too far, so it wasn't too much of a struggle to find his way back to the surface. Gasping for air, breathless not only from the run but also from the fall, Ianto broke through the surface of the water, panting as he looked around for the other man, treading water as he did so.

"Holy... Christ," Ianto said, looking up at the cliff that they'd come from, the sounds of the monster there, then back to Sulu as he finally realized that...they'd actually escaped from the thing successfully there. That it'd worked.
