What was the 'meaning' of the final scene?

The final scene, where at first it seems like Leticia is going to confront Hank on the truth about his former job, but for some reason, doesn't. Look at her body language, she is dealing with life before her before Hank, the relationship to that point, and looks how much Hank has grown and she has grown. That semi-smile at the end? She's made her choice to stick with Hank.

I was thinking the same thing. I thought her expression was great when he fed her some of the ice cream, she knew he loved her at that moment.

What I took from the scenes is that Laticia discovers the drawings by her former husband, puts two and two together about Hank's previous occupation and his part in the former husband's execution and she is enveloped by a trapped feeling. Hank returns and she is speechless as he questions whether she is alright, nodding yes slightly in answer to each of his questions. They then move to the front steps and as Hank shares the ice cream with her and she feels the genuineness of his caring for her and realizes she's not trapped if she wants to be there. And she wants to be there.

I think she was extremely upset when she realized the connection to her husband, but that in the end she decided that being taken care of (in all ways) was more important than confronting Hank. Obviously, eventually it will come up.

I thought it was about accepting that the past happened, and it needs to be put behind her, and the future is waiting for her.

It means pretty much what Hank said - that they're "going to be all right."

I don't care much for the underdeveloped nature of Hank's character, and that we never see him break down. We never see him cry over his son or have any breakthroughs. While it is disappointing, I think they left that up to the audience's imagination to assume. I think it can be assumed that they'll continue to make a home out of Hank's house, they'll probably marry eventually, keep developing his new business (the gas station), keep setting up house, eventually hang up pictures of their kids, maybe have one or two more of their OWN children, and... Hank will eventually get in touch with his feelings and heal. They'll help each other heal.

BB Thornton loves Halle Berry at the point of the final scene. But If you want to think for the sake of thinking, i dont think this love would last forever

Halle gets a good deal in life, and BBT isn't very smart or special so he's got a good deal with a hot woman 10 years younger. Thats love in most cases, unfortunately.

Darkness lies an inch ahead

I think one important thing that is easy to miss is that the fact that Lawrence drew pictures of both Hank and his son, implying that Hank's relationship with Lawrence was not one of disdain. Rather, Lawrence must have considered Hank and his boy "friends" -- or the closest thing to it for a man who's hours from being executed.

Therefore, after the numbness subsided, she probably understood this to mean that their lives were intermingled more than she even thought possible. Their relationship was perhaps in some way a product of destiny running its course, even sacred and beautiful in its unpredictability.
