Do you think Remus ever managed to prompt Virgil into experiencing his butterfly eustress state?
No doubt there was a lot of anxiety and panic Remus regularly brought on, but Virgil even admitted that both of the twins make him overreact in a lot of similar ways.
Where Roman embodies the fluffier aspects of romance, Remus obviously embodies the way less PG forms of it which definitely cause their own form of distress whenever they're discussed in isolation/theory (see: WIDS)
But I wouldn't be surprised if Virgil was subject to the butterflies brought on by arousal once Remus' domain is actually put into practice irl by c!Thomas.
I wonder if, post Janus' acceptance where Remus is begrudgingly allowed around the rest of the sides more and more, Roman ever becomes privy to Remus and Virgil's weird past history as pseudo exes who used to have flings now and then to let off steam during said butterfly episodes.
Could maybe spark some sibling rivalry and jealous!Roman fodder...
Just...food for thought.
