Mama - yes, they DID meet but not recently - only in the beginning.
She is out right lying, she told Dick and Daniele that Kail and Eric have been in an alliance and she is the middle man, that has NEVER happened. Kail and Eric are not in an alliance. Dustin is the one who told Kail that she was safe.
Also I think based on Thursday's show that Eric only has to put up ONE contestant chosen by America - and we still aren't 100% sure if he has to do it or if he can refuse since Julie said in the beginning "for every *insert number, i can't remember* of tasks that Eric completes, he will earn 10, 000 dollars" so who knows?
