SHERRY: Christopher, you’re here! I can’t believe you’re here. I didn’t think you’d make it.
CHRISTOPHER: Are you kidding? You think I’d miss this?
Sherry is being wheeled into the delivery room when Christopher rushes to join her at the last moment. Christopher says he wouldn ‘t miss this, but of course, he already did – he missed Rory’s birth. It must be difficult for Lorelai to witness Christopher showing up for his second daughter’s birth when he wasn’t there for the first. She’s certainly looking rather pouty about it.
Then again, we never see Christopher’s point of view. Did Lorelai tell him she was going into labour and needed to go to hospital, or did she just leave without telling him? Was he given the opportunity to accompany her, or did he simply not know? This is never made clear.
