Once it felt as though Sherlock was comfortable enough with the situation, Will began to drift further away, doing his own exploration. He mostly searched for any litter that wouldn't be of use to the environment. He'd look back from time to time, just to make sure, but nothing more than that. Eventually another big-mouthed fish took great interest in Will and he was about to have a new buddy when...

Yikes. Will's attention turns immediately to the upset, fish pal quickly swimming around behind him for cover. Will looked first to the surface, then followed down to Sherlock, eyebrows knit together and head tilted as if to ask that you? without actually opening his mouth...kinda difficult to talk to anyone down here, he does what he can.
