There's this huge home made feast and Chinese take-out, and before Shelli even dug into any of it, she made up a plate for Audrey and took it to her room. Shelli is the most kindhearted, genuine person in that house. She is a lovely saint, sent from the very Heavens above to watch over this cast.
Also, Jeff was telling her about an alliance earlier, she called him out on hiding stuff from her.

He was totally taken back by her catching on and calling him out. Guys, seriously, do NOT sleep on Shelli. She isn't as dumb as she comes off- she just doesn't want to be threatening.
