Harker thought about what to do. Something really was up with Roland, and he doesn't feel comfortable just letting him risk his life in spying on Victoria while also dealing with whatever this was.
Should he ask to send him back to the ship? No, Roland would never agree to that. Plus, no one else thinks something was up beside Harker, and they won't believe him without proof.
So the best thing he could do was to keep Roland close and watch over him until he could figure out what's happening.
It would be a bit hard to juggle that with spying on Victoria and maybe An Xin, but Harker grew accustomed to having to deal with several things at once. And when he needed to be in two places at once, he just had to divide himself.
Though he was a bit more hesitant to do that after what happened to Hanker. Speaking of that clone….
