When you use Influence to enhance a social check, all you're doing is potentially adding additional successes and advantages. There's nothing stating that it pushes the capabilities of those skills beyond what is normally possible. So if Ray was doing nothing more than making a boosted Charm check in the above video, then it should have been possible for her to do the exact same thing with a really lucky Charm roll without any help from the Force at all. Now I'll admit that guys are prone to doing stupid things when pretty girls are involved, but I think the idea that she just charmed a loyal guard into releasing her and leaving her with a weapon is a little silly.
This seems to tie into a decades-old argument about what social skills should actually be capable of doing. Some seem to think that social skills are a form of mind control; and that if you have enough ranks or you roll a 20 (or whatever), then you should be able to talk a king into turning his kingdom over to you. Others, of course, strongly disagree (especially GM's).
