Judging from various aspects, Lucas Quinn is certain that Charlotte Allison and Caroline met each other when they both became targets of hunters back then.
Presumably, they formed a deep bond during those life-and-death moments, which is why he and Charlotte Allison's trip to Country Y included mobilizing elite operatives from Eork to follow Charlotte's command.
Even Paula can be sent over to protect Charlotte Allison; at that time, he should have known how deeply Caroline trusts Charlotte, to the point of allowing her to freely command her most trusted elites.
And Charlotte Allison...
Why would she choose to use Caroline's people instead of him, who is so close at hand?
The answer is all too clear...
She doesn't trust him or his people, and why doesn't she trust him? Why did Caroline find Rocky...
It's because she found out about what he kept from her with David Blair and Morgon Sheldon at the Mountain City Emperor's Tomb.
He is investigating this matter, and so is she.
