Completely Useless Splatoon 2 Headcanon:

Pearl is nearsighted

1) she can’t read the teleprompter herself for whatever reason, and has to ask Marina to do it for her

2) when you prompt them into waving at you from outside the square, Marina’s the one who takes notice of you first - Pearl first has to notice that Marina sees something, she squints around in your general direction for a minute, and then sees you and strikes a pose

 also speaking as someone who’s constantly been told I constantly look really pissed off when in fact i’m just squinting cuz i CAN’T FUCKING SEE, i relate to Pearl on a spiritual level
