Is Robin ever getting out of the Swiss Hosp.? Why doesn't anyone mention she is alive?

I'm not sure. The original plan was Kimberly (Robin) was never gonna come back to the show she wanted to start directing instead. How ever I guess she realized that so many people have missed her she decided to come back for a few episodes here and there. Although I did read somewhere she'd be back for the nurses ball so I'm hoping this means she escaped or was rescued. And sorry for the rant but I do hope this helped you. :)

Probably but her marriage will be over and Patrick will have already moved on with Sam :~)
