I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
The Titanic issue was to show him how time works, and how it could be manipulated. So now he has a choice: give Satan the symbiote he has, and he can be with his dead wife, and be human. Truly be with her.
Compounding his grief, and his need to find Wanda, is the fact that she was pregnant with his unborn child.
It makes Terry, her current husband, telling Al he was jealous because he never had kids with her a tad ironic. And it can't help but make me think what I originally did when I realized he finally managed to impregnate her: that this is a little bit about his manhood. I have good reason to believe this, however, as he knows that Wanda always wanted kids, and when Al first comes back as Spawn and realizes she had Cyan with Terry? Well, he thinks that the problem was with him and it makes him feel like a little less of a man.
I'm just saying, there are complicated issues at play here. Al loves Wanda. He thinks of her as his wife - not ex - despite the fact that she's remarried. He would go after her regardless. But there's a desperation here that always felt... off to me. Until I remembered that line.
That being said, I love how he managed to protect Terry's family. Just loved it.
And that end scene, with the demon and the big bad? I can't wait to see the repercussions from that play out.
