Something stinks!

Why is Sheila wanting to constantly argue with Adam knowing he'll have
the power to send her home Wednesday? The night Sharon and Ryan got to
watch that movie outside, and Sheila and Adam was inside lock down, Adam
told her he was going to let Ryan think he would go along with who ever
Ryan wanted to evict and told Sheila he would evict Sharon instead of
evicting Sheila like Ryan wanted.. At the time I assumed Adam was just
blowing sunshine up Sheila's ass, but now i'm not so sure.
