1. Johnny Mac makes his way back into the house.

Along with other jury members Shelli, Jackie, and Becky, Johnny Mac competed with the current BB17 Houseguests in the "Dizzy Land" HoH endurance challenge.

After hours of spinning around in circlesliterallythe rock-star dentist managed to outlast the other Jury members, which left him hanging around with Vanessa, who promised not to put him on the block if he agreed to let go before she did. Johnny Mac fell off the rope before the deal was solidified, but it didn't matter because he still snagged a place back in the house

Good thing John didn't have time to unpack.

With Zombie Mac back to eat some brains—his words, not ours—most of the Houseguests feared for their safety in the game. 

Meg and James were definitely scurred about being the dentist's next targets. However, Austwins seemed a smidge less worried because Vanessa, one-fourth of their Austin's Angels alliance, was just crowned HoH and they hoped she would throw John right back on the block. 

Unfortunately for the trio, it appears the Vegas poker player has decided to align herself with an unlikely ally—hint: Johnny Mac—which might affect their master plan. 
3. Always respect your elders.

This New York City server might not win comps, but she's definitely won the hearts of her fellow Houseguests—especially James, who loves nothing more than playing caretaker to the technologically stunted 20-something.

"The bright side of all of this is that everyone loves their grandma," Meg said. "So you can't vote out #GrandmaMeg."

Or can you?

Austin finally popped the question! (No, not that question. Geez.)

He asked Liz if she would be his girlfriend, and she said, "Yes!"

Looks like Zingbot might've actually brought these two closer. However, Liz insists the couple's status change is contingent on Austin breaking things off with his existing girlfriend after exiting the house. 
5. The remaining Goblins go on the block.

Instead of repeating the same nominations from last week, Vanessa appeared to go rogue by putting up Meg and James. She claimed it wasn't personal and she was only doing what was best for her game, but that didn't make the blow any easier for the last two members of the Goblins alliance. 

How will the power shift now that Vanessa's working with Johnny Mac? Is there a backdoor plan in the works?
