SPOILERS BELOW:
Call me a romantic, but I don't like the fact that the "Dad" was kicked out of the house, because the "Mom" can't adjust to him being back in their lives, and/or she can't decide whether she wants to be with him or the "Boyfriend."
Sure, he was there for them (for the last 3 years), and they all thought "Dad" was dead, but it was through no fault of his own that he was "missing" for 5 years
And yes, there was mention of a little "tension" between them before the plane disappeared, but that's par for the course, when a couple has a sick child, who could possibly be dying.
While the "Boyfriend" seems to be a really nice guy, he needs to move on and back off, and tell the "Daughter" to go to her "Father," when she needs advice, comfort, or whatever.
But then again, without that
drama thrown into the mix, the storyline would be boring, wouldn't it?
Now that I think about it, I guess the writers accomplished their goal: They made me want to "stay tuned" to see how this situation plays out.
Edited to Add: Oh, and who else didn't see the "Sister/Cop" and her "Fiance" getting all "lovey-dovey" from a mile away?
