We already know how Kitsunami would feel if Surge started dating someone else, so what about Surge
How would Surge react if Kitsunami started dating someone? (Anyone of your choice)
Oooo!! This one is a tough one if only cuz Kit only has eyes for Surge.
So for the sake of amusement on my end, I'm going to say Surge mistakes Kitsunami being nice and comfortable around a person for him dating anyone else.
Kitsunami has been... Getting closer and more relaxed around a weird guy by the name of Eclipse. He's an alien who claims to be Shadow's brother and doesn't take kindly to Surge. And this? This is the issue. Surge is fine with Kit being iffy about her dates. Hell, she can forgive his possessive nature and his occasional killing sprees due to it. But... Kitsunami giving his attention to someone completely different than her?
It feels... Wrong. It's not inherently bad and she's not jealous at first. At first she's delighted to see Drippy have someone outside of her to spend time with. Hell she even calls them cute and asks for Eclipse to stop by for dinner. It only makes sense that Surge allows Kit to have his own disaginated boyfriend. Especially seeing as he allowed her to keep some people around he didn't deem as a threat to his station.
But that's definitely short-lived. After a few months of teasing Kit and supporting his new found "romantic relationship". She... Starts getting touchy. By this point Eclipse has made it abundantly clear that he dislikes Surge's existence. And she... Really doesn't like that.
The more time Kit spends with Eclipse, the more it annoys her. After all that's her Drippy. Not to mention... It's just... Boring to be by herself for long periods of time. Leading to her being alone with her thoughts and swiftly causing a spiral to start.
Eventually it hits a boiling point where Kit confronts her about how she is doing since she's been really snappy and mad at him. And when she snaps that she doesn't want him to see Eclipse anymore, he just paused and agrees. Earning a lot of confusion from Surge. Because Kit was supposed to defend his relationship with Eclipse. He was suppose to fight her on it like she does with him.
And when she rightfully questions him on it, Kit shrugs and admits that Eclipse was nothing more than a friend. If Surge wants him to stop being friends with Eclipse, Surge will always come first. Which makes Surge feel bad cuz she's forcing her Drippy to not be friends with someone, so Kit decides to make it up to her. Taking her to her favorite spot and then treating her to a nice long session of burning down an Eggman base (therapy is expensive. Destroying Eggtech is free!!).
Anyways, Surge and Kit would end up scheduling more organized time for her and Kit vibing and Eclipse may or may not be around in their life tho cuz Surge gets jealous pretty easily if she's not dating the person too.
