Can you handle both of us? (слэш)

Bucky and Winter are both in love with Tony, and the three of them are enjoying a peaceful and lovely relationship, working on each others problems together. Bucky can't handle being around Steve as the man only talks about the past, trying to get the good ol' Bucky Barnes back and get rid of everything Hydra did, including Winter. So, every time Steve is around the one in control is Winter.
Steve thinks Tony made something to control Winter and Bucky, so he asks Wanda to make a separation spell. It works and now there is two Buckys. The winter soldier and James Barnes.
Will Tony be able to handle both super soldiers?
