It would cause a firestorm and thus will never happen, but imagine if having Tran stuck in the back of her brain affected Shan's sexuality? Somewhere in the back of her noggin, when she would think of a boy, Tran would be thinking 'uh, gross, not while I'm in here, please...' and when she sees an attractive woman, Tran's nodding his approval. It's all subconscious, he's not driving the bus, or even talking out loud where she can hear in her brain, but she might well have been getting some vibes, and if his feelings on the matter were stronger than hers...
Now that they are apart, suddenly she doesn't like girls anymore, because she was being influenced by the passenger in her backbrain. And the internet catches on fire because of 'lesbian erasure' or whatever, despite her character hardly ever getting to be one anyway, since she's been more or less in limbo for decades and mostly been gay because she says so, not because she's had a string of girlfriends or a long-lasting relationship with another woman.
Or, even more fauxrageous, Tran wasn't shown in 'his' new body being resurrected because they are saving it for a big reveal. He's spent the last few years being a passenger in a girl's body, and 'he' no longer identifies as 'he,' so next issue, we meet Shan's new *sister.*
But does Marvel have the courage to have the person named
Tran be y'know...
