I bet there was going to be some type of sparks going on in later episodes
Summer Glau played her character Orwell that way because she always do that. But while the writers hinted that Orwell could be attracted to Vince (hence the wedding scene in episode 7), David Lyons as Vincent Faraday showed no clear indication than Orwell was more than a friend to him.
Since Vincent's purpose in life was to get his family back, I don't see how that leaves space for a romance between him and Orwell. Don't get me wrong, I'm a vince/Orwell shipper but I don't see how this could be done, unless his wife dies or remarry, and I don't think the show was going into that direction.
There's a reason why the scene in which Vince was creepily staring at Orwell performing aerial silk has been deleted.
