There's a lot of talk about a third Bill and Ted movie, and idk where I thought of this but I thought it'd be cool if it was about little Ted and Little Bill going on an adventure to save their dads who've been kidnapped, only they need some help so they enlist the help of little Ted's younger sister/Bill's daughter who goes on the account that they "owe her one," only little Ted's unhappy because he thinks his sister's lame but little Bill reassures him she's cool. Then later on she has some real talk with little Bill about how they've always been afraid they wouldn't be excellent or fearless enough to please their fathers and little Bill finds out his best friend's little sister has a crush on him and realizes he's got a crush on her too. Then at some point little Ted risks his life to save his sister and tells her he thinks she's pretty cool. After everything works out at the end the boy's assume little Ted's sister is going to use her owemeone for little Bill to take her to prom but instead she uses it to get the boys to let her into Wyld Stallyns 2, since using an owemeone to get a date would be most heinous, and she wouldn't want a date on account of an owemeone since only real ones count and little Bill ends up asking her out anyway and little Ted has a new found respect and admiration for his sister plus their dads say they're all proud of them for being so excellent no matter what adventures they have.

It explores a sibling relationship, a platonic best friends relationship, and a more romantic relationship and how the three would fit together, and it would also have all the fun time travel-y stuff

I just thought I'd share that, I'll write up a full thing soon
