it sounds like Jesse, Derek, Alejandra, Kaela, Maddy and Paras are all together (according to Hamza)
The entire house is against Andrew and Hamza so Ryan feels pressured to nominate them.
Andrew is pissed at Erica because he feels betrayed by her (she apparently gunned for him during the HOH comp), and Erica is justifying herself by telling Andrew that she couldn't trust him after he tried "flipping the house" (whatever that means).
Hamza suggested an alliance with Andrew, Ryan, Erica, Johnny, Paras + the 2 noobies which would swing the numbers in their favour.
IDK anything about Olivia. Nobody has mentioned her yet.
I think I saw olivia talking game with Alejandra so they seemed kinda close to me. Andrew is making me uncomfortable with this following Erica around so I cant even feel sorry for him for being the house target. I like hamza though.
