OH MY GOD OH MY GOD OH MY GOD.
IRINA!!!
Without reading spoilers, without reading anyone's entries, without reading anything, I TOTALLY CALLED IT.
At first, when I heard the voice say "You're sure it won't harm the baby?", I was like "OH MY GOD, IT'S JACK!". I paused it, turned to JB and asked if she recognized the voice.
"Yes!" she exclaimed, "but I don't know where I've heard it before. Early, early on..."
"Imagine it saying 'Mr. Tippin.'"
The lightbulb went off over her head. "Wait, but wasn't that... Jack?"
"YES."
But then, when they showed the silhouette CreepyDoctor was talking to, behind the glass, I was like "That's not Jack. That's a woman. OHMYGOD, what if it's IRINA?!" This was confirmed not to be Jack when they got word of Sydney's abduction. Did I actually think it would be Irina? Not so much. I thought if it WAS Irina, we'd only find out two or three episodes down the road.
BUT IT WAS IRINA AND OH MY GOD SHE'S BACK AND I STILL LOVE HER.
More thoughts when I've calmed down.
