“I think it’s [Theseus and Newt’s relationship] born out of love. Theseus is the complete opposite to Newt – he’s the Head Auror at the Ministry of Magic, he’s an establishment man, he’s risen through the ranks very quickly. Newt’s completely different, he’s Nomadic, he’s out there and Theseus is worried about him, he wants him to be part of the society that he’s risen through and also there’s a crisis coming. Boiling point is about to reach and he wants him to come and fight with him. So he’s trying to protect him rather than push him away or anything and actually that’s the opposite – Newt’s not a hugger, is he, no, and Theseus has kind of got him like that [in a tight hug], and that’s not going to work. He’s got to change his tactics. I think if they both, the similarities between the two is that they’re both incredibly stubborn, true to who they are and I think that’s their lesson, if they loosen up a little bit, if they’re a little bit more free-flowing, then they will come [together].”
