Splatoon - One of these days, Nintendo... One of these days...

Calm yourself. Honestly, if she just showed up at the end of the single player campaign in Octo Canyon or something so you can interact to her like you did with Marie, that would've been enough. What people are mostly bothered by, is the fact that she's virtually non-existent post singe player. It's like as if you played a Super Mario Bros. sequel, except Mario only has about as much screen time as he did in Luigi's Mansion. Though, I'm still seeing possible future single player potential for Splatoon 2, so something may happen.
