No surprise, it's Russell and Lydia.
Lydia is not being shown on the feeds at all (diary room?), while Russell is trying to act like it's not bothering him...outside of a crack about being nominated "by my own team".
Russell is now up in the HOH "congratulating" his teammates (Chima, Natalie, and Jessie), and tells Chima not to feel bad. "I don't feel bad at all."
