why Green Lantern needed to leave Earth for personal reasons?

It goes back to last season's finale, when GL had a really, really bad breakup with Hawkgirl.

Also, is Lex Luthor no longer a villian, or was he just blowing smoke up that reporter's ass?

Most likely the latter, but then again LL did save the Earth, as Dr. Fate pointed out.

I was a little (okay, a LOT) confused about Hawkgirl showing up at the end of JLU. Was she just hanging out at that turns-to-an-ankh dude's place? And if so, why?

Well, we're probably not meant to know the "why" yet, but it's still confusing to me.

Also, who is turns-to-an-ankh dude, and is he a good guy? I was assuming he's a good guy b/c he was on the JLU space station, but then the end seemed a bit ominous. Or at least grey.

See I saw last season's finale, but I didn't get why GL would think Hawkgirl was on the GL home base world.

Also, I got the impression that the Ankh guy (Fate?) is good/neutral.

See I saw last season's finale, but I didn't get why GL would think Hawkgirl was on the GL home base world.

I got the impression that he's not looking for Hawkgirl, he wants to get as far away from her as possible.

I thought what Tom thought. Though it would have made more sense earlier in the season.

Steph, you mean Dr. Fate? Because if I try to explain that character, I'm going to get all kinds of confused, as I don't know which version they're using for JLU. Though the current continuity comics Dr. Fate would be hanging with Hawkgirl because she's his mother reincarnated, and also his cousin. Oh, and Current Comics Dr. Fate is Hector Hall, who you may remember from Sandman as the deceased husband of Lyta Hall, father of Daniel, he who is now Dream of the Endless.

The animation version of whats-his-name. He originally made an appearance on Superman: The Animated Series.

Thanks, Tom!

My goodness that is sooo confusing.

Well what can you expect from 60+ years of retconning?
