Momo: "Mr. Aizawa, sir? I think I caught a glimpse of Izuku heading towards the shipwreck with Ochaco-does that help?"
Deku and Uraraka were going to the rock Tsu liked to sun on, having found a whole bunch of human treasures in the shipwrecks below. Tsu could usually tell them what they were-although, sheeee didn't really know either-she was just going off of what she had observed-Deku saw Tsu and waved at her, smiling brightly
"Hey Tsu!"
