I‘m still not over the interviewer asking them the same question in separate interviews at the S3 premiere („what three things do you think people should give more thought to?“), and both of them listed exactly the same things (the environment, tolerance and empathy). That‘s what matters, right? To be on the same page with your partner when it comes to the fundamental things in life. To share the same outlook on life, as Caitriona once put it (referring to her and Sam, mind). That, along with trust and mutual respect builds a solid base for any relationship.
