I loved the Robin/Marshall friendship

I was always a bit sad, we didn't get to see more of just the two of them. They had such great chemistry (besides that one episode, where they were supposed to have that awkward dinner, which annoyed me a bit because they had been together alone before without it being awkward)

I loved in the finale when they said goodbye to Ted, and Marshall were holding both Lily and Robin.

I wish they would've exploded their friendship a bit more.
