Now more reruns appear on 2/20, back to TJ, Lisa, Christina trying to get her photos off the net. Since it's just late Oct right now, and they ended Jan 9, that's about 10 weeks to fill, minus the holidays when they probably break for home a bit. Lisa 1 has "30" days. Just a week or two or three of reruns to get to March, then they only need about 9 or 10 weeks of shows..... and it's over in May.
I predict Lisa will be back or featured for ratings near the end of the season, to graduate with the others, one giant party. Maybe a final cast party....bigger than any others???
Somewhere on a spoiler someone mentioned Kim was only there for 3 weeks, a relative or co-worker said that in a post. It doesn't seem that Jodi has much to work on, Jill will probably graduate after next week-long Andy Paige visit, then reruns, then to the finish line. Kelly looks like a massive project needed, she'll probably be the huge character for spring shows.
Just guessing. Maybe the reruns are a cost savings feature too.
