Ok so I was just going through Egger's Facebook reading comments, and found something interesting. She says a few times "filling in" on Weather Center, long after we started speculating Alex was let go.
On October 12 @ 6:10pm, she commented on a wall post and said "...back to filling in on nights today-Friday"
On October 12 at 6:14pm, she commented on a wall post and said "...I'm filling in on the night shows this week, Tuesday-Friday. 7 to 10pm eastern"
Also, someone posted and asked if Egger knocked Alex out of the line up, and Egger responded and said "Hi John, I'm just filling in where I'm needed. I'll be on Day Planner with Samantha Mohr on Monday."
