Tense

Four used to be proud to call himself a hero of Inkopolis. In retrospect though, all he did was solve some family drama and live through a story someone's already gone through, right? He's felt jealousy towards Agent 3 for not being there when Callie got squidnapped, yet can't find it in his heart to tell anyone about it. After all, if it wasn't for that old coot and her going out and galivanting around, they never would've discovered Eight... And then she saved Inkopolis.

...He hates these feelings.

Love

His bitterness against Eight was one slowly overcome by love. Though he remained spiteful over the fact the enemies he faced were suddenly appearing in Inkopolis City by the dozens with nobody even doing so much as batting an eye, he slowly warmed up to Eight, eventually seeing her in a new light when she sympathized with his struggle. With all he's tried to keep her from meddling in his business, she always finds a way to worm her way back in. And... He really appreciates it.

When the first Big Run approached, Eight put herself up to the challenge of performing alongside Four, though he vehemently tried to deny her going anywhere near something she knew little to nothing about. But... They did need a fourth member. A temporary one, but still. Eight ended up learning the ropes quickly, impressing Four beyond belief. He admired how strong she was in the face of adversity, and was proud to bring home a gold trophy for the Goldie Crew after all was said and done... As well as some newly developed feelings he couldn't plan for.

Familial

Despite their differences, Four clearly cares deeply for his crewmates. Era and Chim, though complete opposites to the Inkling, never fail to surprise Four with their undisputed loyalty towards their line of work. Whilst he's still... Rather tense with Era due to their less-than-favorable history on the frontlines, He's the only one to ever see a more vulnerable side to her, following a tragic accident that costed them a cherished teammate. Chim, on the other hand, for how much she whines and sobs, is still a reliable asset and simply just... Too nice to hate! (Secretly, he hopes she can find a better job.)
