I wouldn't say Jo's leaving was *the* saddest, but it was pretty poignant the way it was done (the bit at the end where the Doctor slips away in full realisation that he won't be noticed - and isn't - reinforcing his loneliness and alien nature.)
Having spent so long with Jamie and Zoe, I thought the way the timelords wiped their memories of the Doctor before returning them to their own times was pretty sad.
I suppose Adric's departure was intended to be sad, but for me it was a huge relief.
Sarah Jane's departure was even more touching for me the second time round, with her "say it this time" speech.
