I just checked NBC's website and the last 4 episodes are still there. They were streaming the whole season before last night.I think it wouldn't hurt
In my case my memory is not as good as it used to be and considering the last episode was like what 8 months ago??
At the start of this show, there's a recap from previous season, but nonetheless, as the show started I couldn't identify one of the characters, then my memory very slowly started to catch up....
