I love Currie Graham as Walter Mashburn in both the episodes he appeared in.
Actually 3.7 "Red Hot" is one of my favorite episodes. It was great to see a different side to Lisbon and to have her have some fun. Can't get over the ending scene! It was just too great, especially how enthralled Mashburn looked at her. Felt a little sorry for him, he clearly wanted more. But that's our Lisbon )
I think he has great chemistry with both Jane and Lisbon and I enjoyed every minute he was on screen.
I think the writers could have leave little hints about his return from Europe after "Red Hot" though - it wouldn't have needed to be super obvious, but maybe Lisbon receiving a card or something. I was a little disappointed they just totally forgot about him afterwards even if it was "just" a one-night stand.
So I sure hope he will return for some more episodes in future seasons. It's be great to see how both Jane and Lisbon would react.
Any other Mashburn or Lisbon/Mashburn fans here?
