If youāre still doing the character interaction, Edge and Plum?
Bad ship. Bad, bad ship. I donāt think Edge would be interested, but I think Plum might be interested in him. Aside from his criminal roots, Edge is just about everything Plum could want in a partnerāor thinks he wants. (In reality, nothing Edge did would ever be satisfactory for him. Heād find the most minute things to criticize and heād verbally abuse Edge because heās a hateful little monster.)
I see this more as an āunwanted suitorā situation. Where Plum is continually flirting and offering him gifts and compliments, only for Edge to grow more and more uncomfortable as he tries to remain polite while maintaining his distance. It could go pretty badly, if Plum ever gets any leverage over him.
Edge would keep things between them professional and curteous. He wouldnāt want a close relationship because he finds Plumās lack of empathy distasteful. Plum, meanwhile, would admire Edgeās efficiency and strength. Heād want to bring him under his wingāinto his debt or into his bed. Edge would be too savvy to fall for Plumās flattery and flirtations, but Plum would definitely try.
