Regarding the bolded.. Rosita.. when she said, "Fine.. I'll go by myself!" I was like, Bye Felicia!!
And, I wonder why the Saviors agree to meet Ezekiel outside of the Kingdom when they're all the time rolling up in Hill Top and Alexandria??
like the pp said, Ezekiel worked out a deal with Negan. He didn't want the Kingdom to know they are providing stuff to Negan. For some reason, the saviors agreed to meet off-site to take the payments. I guess Ezekiel wants the people of the Kingdom to feel safe and like it is a sanctuary. I would not be a bit surprised if the saviors just do what they want and bust in the Kingdom at any time, but I guess as long as Ezekiel and his men keep up their end of the bargain and deliver goods, the Saviors have no reason to break the pact they made with Ezekiel.
