It can't stick. She could be off having her real life baby and they needed her gone for a bit. At first I thought it was a ruse to get away from Red since it happened just after she talked to Mr Kaplan but some of the things they did at the end they may not do to a "healthy" person so now I'm not sure.
Well, this is obviously timed for her maternity leave. Either way, Red isn't in the know so his reaction to this is going to be explosive to say the least. Red on a rampage should make for interesting TV.
