Julien's still trying to adjust to his eyes, stupidly sensitive and high-frame-rate and all. He's reluctant to go outside alone because he still tends to get distracted and shaken.

Otherwise idk! He certainly might get affected by the water, and since he can't laugh normally anymore he will just sort of... gasp weirdly. Clearly someone needs to see that.

The water looks slightly odd to pigeon eyes. If any effort is made to track down the source of the contamination, he could be useful, but it's not something he'd try and organize.
