An interesting relationship with Newt. You’re his brother and about to marry someone he was in love with. This is complicated:

“It is complicated but I think that the important thing to realise is that it wasn’t a full relationship. It was a companionship at school and I think he’s of the understanding that it wasn’t as severe as it’s being made out now [in the media]. And he provides something for her that Newt doesn’t, with their similarities, Newt and Leta. Theseus is the complete opposite to both of them and provides a stability and an acceptance and love and a support that is needed in a relationship and they both give it to each other. And he’s risen to the top of the ranks at the Ministry, he’s the Head Auror, and is fighting the good fight in the way he knows how. He’s incredibly stubborn and wants his brother, who he understands to be a more powerful, special wizard, to join the fight on his side, through the establishment, which obviously Newt is repelled by.”
