I don't see Jemma believing him though. HOW COULD HER TEAM NOT CARE? I don't see how Ward can be persuasive enough either (yeah he's manipulative, but Jemma is smart - don't be weak our precious Jemma, stay strong always), especially knowing the type of manipulative person he is. Unless Jemma isn't the same person, if the stone changed her somehow. If anything, Jemma could be tagging along with Ward as a survival mechanism, going along with him because she knows she can't do it all alone and he's resourceful. That is IF Ward does indeed find her first as we speculated. But who knows! I don't see Jemma becoming another Cara because she knows too much of his bad side, the things he has done.

I missed the part about the agency. They may have better persuasive tactics. Convince her they know where her friends are maybe. And it be all a lie! I still don't see Jemma being easily swayed to believe them either.
