Whatever you end up doing, love it.
So Seb has been away filming for Infinity War, so your son hasn't seen him for some time. James gets really excited when you tell him that his dad is coming home. When Seb walks into the door and you say that daddy's home, he starts to cry and say "that's not my dad, I want daddy". Seb and you are confused and then you realise that it's probably the beard. James has not seen him with the beard. Seb starts talking to James in Romanian when he screams "DADDY".
