yeah, it is crazy how it happened, but the meat of the episode was literally the last 15 minutes. I am sure I will miss some details, but let me try:
1. Darrel, Yumiko, Michonne and Carol left the fair to go and help protect Hilltop if needed.
2. Alpha pulled Lydia out of the theatre and basically told her she was not worthy of being a whisperer and left
3. the top 4 got captured the usual way (fighting zoms, then the whisperers all filled in).
4. Alpha led Darryl from the group (who agreed to not fight back when Beta came up to him and said he wouldn't repeat to drop his weapons). she basically spelled out the rules for how they will go forward. basically she told him to not invade their land, and that they would be fine going forward. she then told Darryl he can leave and meet up with the other 3 up north
4. they showed the 4 meet up, and head to Hilltop. on the way they saw 10 pikes in the ground, and all 10 had the heads of people from the group. the highwaymen, some red shirts, Yumoiko's buddy who was the musician, Edith, Tara and Henry
5. oh yeah, they also had a "feel good" clip with Syddiq who was also captured but was let go on purpose to tell the group what happened.
I have to guess there is a clip on youtube or something with the last 15 minutes because it seems a lot of people missed it
