I love the idea that while they're together, Liam starts researching the ace spectrum and all this stuff to understand Theo better and then the open relationship thing comes up. Liam asks Theo what he thinks of course but only out of curiosity and Theo GOES CRAZY. Literally. He starts having all sorts of complexes about Liam and their relationship, about how they shouldn't be together, about how Liam wants to cheat on him but is too good to do that etc... and of course Liam knows NOTHING. Liam has even forgotten that he ever asked the question and in the meantime Theo is going through a total crisis.
I think it's basically canon that at some point Liam makes a comment about someone like a teammate of his (maybe like "yeah the new goalie, Mason says he's handsome) and Theo has a panic attack and Liam obviously gets scared and worried because he has no idea what's been going on in Theo's head for WEEKS and nothing, I love an insecure king.
