I love him. There is no way that MARTIN is in Benedict's shadow. There is a difference between the actors and their characters. While you can call John Watson a "shadow of sorts" you cannot place MARTIN there!
Martin is throwin gang signs but it looks like Ben is just telling us all to live long and prosper! <-- Actually, long story short, but Ben's sign means "don't forget to be awesome." People need to read up on nerdfighters, and our signs, yo!
