In terms of my relationships with a lot of the adult characters, when I was working with Harrison, it wasn't like a verbal agreement, but we both understood that because there was this constant tension between our characters, we couldn't say "Cut" and start acting normal. We had to keep an essence of that relationship in our characters off screen which is really important.
