I can totally see Bubbles trying to push Blossom to ask Dexter out. She'd probably argue they're both smarty pants who can't be understood by anyone else and have matching red hair, so they'd be perfect together!
I have my own headcanons about Dexter and Blossom, and one of those is that is Dexter who has a crush on her, but Blossom just sees him as a good friend and a scientist at Utonium’s level. Main reason he decided to help her searching hes sister? To test his devices, to find a missing superheroes, to impress her and because he didn’t want to see her sad.
Dex will wait until the war is over and everything’s back to normal to even just think about asking her out. Also his insecurities will stop him everytime he sees her.
“She’s too good and perfect for me. She’s a superheroine! And… I’m just a little ugly scientist…”
Who cooks: Blossom. She wouldn’t eat anything Dexter cooks. Not in a million years.
Who does the laundry and other chores: Blossom does her own laundry. Dexter has his robots doing his laundry, and he insists Blossom to let his robots do the laundry for her as well, but she refuses because it doesn’t build character.
Who’s more dominate:Both. Gingers are territorial creatures.
Favorite nonsexual activity: Chemistry, perfecting their Chinese, arguing over who’s right and who’s wrong, and complimenting each other afterwards~!
Their favorite place to be together: The lab, and maybe the couch they added in there after their marriage.
Any traditions:Arguing, telling each other cute things in a foreign language before one leaves for crime fighting and the other to a science convention, going out at least once a month.
Their “song”: ”Don’t Be Stupid” by Shania Twain :P
What they do for each other on holidays: They pact not to argue.
Where did they go for their honeymoon: Well, if this happens after the Fusion War, they would go to a science convention in Paris, France, since Paris was the city of the scientific minds on the 1800’s. They would go to Tokyo, but Dexter had a blurry exchange student experience there and he kinda wants to avoid it.
Where did they first meet: Their neighborhood. They lived “exactly 25 blocks“ from each other. ((*Squeals!*))
Any pets: Monkey. Probably Blossom is the only one who’s realized he has superpowers.
What do they fight over:
Do they go on vacations, if so where:Science Conventions sound like vacations to them, and maybe the beach ;)
My headcanon is once the war's over, Blossom would go thank Dexter for helping bring her sister home. Dex not knowing what to say, would downplay it and insists he has work at Dexlabs he needs to get back to. Thinking he blew his chance with the superheroine, Blossom asks him if he would like to come see Utonium's lab sometime and hang out together. Dexter, while shocked, says he has free time now that the day's been saved.
Write headcanon instead of drink and that’s my answer!
