Notes:

Hear me out
This new episode is sort of recap/clip show.BUT there is a reason for it.

TL;DR version
The budget was cut for an entire episode and they had to make a choice:
1) let go a significant number of crew members several weeks early, or
2) make a clips episode
They didn't want to fire people so they decide to do the second option
