Not bad, in fact apart from being a little heavy handed with the friend guilt tripping a pretty decent episode about accidental slip into villainy. I especially liked Janeway's dressing down of Neelix at the end, his beaming smile as he realised he wouldn't be asked to leave, then her knowing smile after he'd left. Without Janeway's smile that last scene would come off a lot harsher, but with that you know she can see just how and why Neelix did what he did.
And I'll admit, when it started with him bugging both Tuvok and Torres, I was worried this was going to be an annoying Neelix episode, as he's been drifting that way a fair bit recently. I'm pleased I was wrong.
