Dr. Hamilton: What did you do with my lab?

Lex: I destroyed it.

Dr. Hamilton: How dare you?

Lex: You're lucky you found a cure and nobody infected can remember anything.
But people are talking. (There are rumours of Beels?)
I'm sure Beels worked for my father, and then there's Chloe Sullivan. (Chloe is another obstacle?)

It means that people are gossiping. I'm not sure who Beels is, but it would seem that their gossip is centered around the entire situation, not just him/her. However, Lex is clearly worried that he will be negatively associated with whatever happened, and the connection to him seems to be through Beels.

Yes. The implication is that she knows something which could damage him.
