“My contract ended at the end of season 6, and choose between signing a contract for two years or continue your career, it is the decision of a lifetime. Especially at this time. I would not doubt that there was rather a reflection on what was best for me. And I am confident of the fact that I made the right decision.”
“For me, the relationship between Lucas / Peyton is one of the bases of the series and remains the common thread of the first season…Lucas has always loved Peyton, and he is faced with this choice. As a viewer, I loved to see that.”
“It’s impossible for me to say that I have learned nothing from Nathan, but it is also difficult to describe what he gave me. I saw him through so much, and now be a good father and good husband.. It’s hard not to learn to be the best man possible. It is, moreover, [what] Nathan tries to do constantly.”
