How about Sublime choosing not to be Marinette's friend and actively avoiding her, but still remaining Adrien's? I think there's a lot of good potential angst where Marinette's obsession with whether or not Sublime will reveal the truth about what really happened to her legs and Sublime's annoyance about her finally blowing over.
I don't know enough about Sublime to make a proper prompt for her, however, some things that'd happen in the scenario where she decides not to be Marinette's friend, but still be friends with Adrien:
• She definitely tells Adrien what happened. Maybe not immediately, but definitely sooner rather than later.
How her legs weren't repaired by the Miraculous Cure. How what happened ruined a great opportunity for her.
• Adrien would definitely be suspicious because her prosthetics should have been fixed by the Miraculous Cure. Things broken prior to someone being akumatized have been fixed before (see Alix's pocket watch and Marc's journal/notebook).
So what happened to make this time different? Did Sublime have to be the one akumatized for her legs to be fixed by the Miraculous Cure?
• If Marinette is worried about Adrien finding out, she's mortified when Chat Noir begins asking LB why her cure didn't fix Sublime's prosthetics.
How does he know they weren't fixed? Did she forget that they weren't? Did she not go see for herself and assumed they were fine? Or did someone tell him? Did Sublime tell someone, and then they told Chat Noir??
• Sublime also definitely tells Adrien what Marinette does isn't okay. How it feels creepy and weird. How it makes her uncomfortable and how she doesn't understand why he doesn't feel the same.
That leads into Adrien rethinking his relationship with Marinette and realizing, yeah... it is weird. It does make him uncomfortable.
And the more he thinks about it, the more he tries to remember what it was that made him fall in love with her, the more he begins to realize that there was nothing.
The moment he said he fell in love with her? Reality was that he felt, well, violated?? He can tell you why he thinks she's nice and can be a good friend. But why he loves her?? Nothing. Or at least, nothing that makes sense anymore.
• It doesn't take long for Adrien to end their relationship. It's messy and both parties end up leaving in tears and with broken friendships.
• I can see Sublime feeling a bit guilty, because she didn't mean for Adrien and Marinette to breakup. But at the same time, she's not going to apologize for helping Adrien see the truth.
• Honestly, bring Heart Fixer in early, but have Tikki have the foresight to remove the earrings. She needs to find a new temp. holder, quickly. And instead of going to Alya or Adrien, she gives the earrings to Sublime.
• Adrien breaking up with Marinette, combined with her being akumatized, makes Marinette double down on not telling Adrien anything, as well as keeping an eye on both him and Sublime.
• For a good chunk of S6, Sublime is Adrien's only friend, because the majority of his old friends either blame him for his and Marinette's relationship failing (in other words, Marinette did nothing wrong and he's a jerk for leading her on) or they want nothing to do with the drama and are staying quiet.
And for that reason, I can easily see Adrien and Sublime becoming a couple. Some of Adrien's old friends get mad that he moved on so fast. They blame Sublime, thinking and claiming she stole Adrien from Marinette.
But the others realize how happy Sublime makes him. How happy they make each other.
And they begin to compare his relationship with her with his relationship with Marinette. Things they notice:
▪︎ Marinette has ditched Adrien during dates, Sublime hasn't.
▪︎ Marinette made a big deal over a stupid kiss, Sublime doesn't.
▪︎ Marinette cried when Adrien didn't show up for movie night, something he very specifically said he was going to do so she could spend time with her girl friends. Sublime appreciates that he wants her to spend time with her friends without him having to be there, and ends up inviting him anyways, because she wants him there. No reason other than that. And when Adrien still insists he doesn't want to go, she doesn't get upset when he doesn't show up.
▪︎ Some of the girls bring up Marinette's pull down calendar with Adrien's schedule and how she knows it for the next 3 years. Sublime doesn't have his schedule, but she knows what's happening during the week because he told her.
▪︎ Marinette stalking Adrien is brought up, Sublime has never stalked him.
Anywhere they're seen together is always planned. Be it they go together or they meet up at the specific location.
• The ones who blamed Adrien and Sublime for Adrienette ending? Apologies are handed out, and they understand why neither Adrien or Sublime want to make quick amends.
• Marinette is definitely the one who takes the new relationship the hardest. At one time, Tikki would have comforted her. But right now? Right now Marinette needs to learn that there was no one to blame but herself.
