Nate/Clark?

Hello, I haven't blogged in a while but While I was watching this weeks episode, It got me thinking. Remember Nate in season 3? (I think) He kidnapped Paige and Emily Killed him? I think there is a resemblance between Nate and Clark from the season. The person who Aria takes photos with and We saw him this weeks episode. The resemblance is not great, But I can see a hint of Nate in Clark. Maybe Clark was Nate's brother or relative. He found out who killed him and wanted to get revenge. I know this theory is far fetched but its a possibility. He wanted to get close to Aria in order not to look too suspicious if he got close to Emily.... I think That maybe this is a possibility? What do you think?
