Very interesting premise. I must say I was thrown through a loop at first, thinking that Zal was Zod's child (

) Of course, then I had to remember, no Zod in LnC, only Nor. I love how she casually drops "abducted by aliens". Oh, if *these* were the aliens abducting people, boy would that make all those "I was an alien sex slave" stories in the Nat. Inquirer more interesting. LOL. At first, I thought she was abducted by Nor's men and she'll bump into Alt-Clark and somehow recognize him as a Kryptonian as well. Or part of the conditions of her release was to spy on the Kryptonian Kal-El at the Daily Planet. That Kal was one of the ones who abducted her (I'm guessing saved her from who actually abducted her) puts a different twist on things. So, Krypton hadn't gone boom-boom yet?
Perry's worries about Lois having a 4 year old son, when she technically shouldn't have one older than 2.5 (counting for 9 months pregnancy) makes sense.
I could see a story with Lois acclimating herself to missing three years (in alt-dimension, I'm guessing?) with flashbacks on what happened to her, while she waits for Kal to join her on Earth. Perhaps a series of vignettes with some flashbacks, so it doesn't seem as such a huge story to tackle (I wish I had thought of that). Take it one day at a time, and don't worry, wherever or whatever QoC writes, Readers will come.
