With Mary Lynn Rajskub about to give birth in real life any day, 24 fans are wondering who’ll replace Chloe as Jack’s go-to geek. Well, they can stop wondering: Sources confirm to me exclusively that she’ll be relieved by none other than the perpetually pouty computer whiz’s ex, Morris O’Brian.

Though the slippery hacker won’t make his comeback in fall’s two-hour teaser “prequel,” portrayer Carlo Rota has just signed on to appear in a handful of episodes, starting around the midday point after January’s official premiere. How will the changeover take place?

Spoiler alert — don’t say I didn’t warn you!

I hear that an emergency involving Chloe’s now-4-year-old spawn causes her to take off for a few hours (i.e. episodes), prompting her (possible) babydaddy to step in. All of which sounds OK to me, so long as Chloe’s kid isn’t being menaced by a cougar. Been there, done that, don’t wanna go there again.

So what do you think? Will you be glad to see Morris again? Or did the lot of him that we got last season go quite far enough? Let loose with your comments below!
