Occasionally I'd feel that the show and the characters were teetering on the edge from likeably unlikable toward just plain unlikable - Michelle would say something brutal to James yet again, or what have you - but it always reeled me back in. Their bark is worse than the bite: Michelle may say horrible things to James, but nonetheless he's one of the group - they're not going to cast him out alone in the world.

And it's the same with Orla: exasperating though Erin finds her, Orla's still one of the gang. And I suspect that if Erin's grandfather ever actually succeeded in pushing her dad out, he'd probably be horrified (though he'd hate to admit it).
