It's not a week.
Hasn't done anything since the PPV, where she lost the titles with Nikki. And if you go back, it was the RAW the week before that, the last she was seen on regular TV. Which is where she wrestled Sasha, which was highlighted by Becky. The match was used to promote the Becky/Sasha match. A throw away. She was not on the debut of SD, not on of any draft days, and not on SD's first normal show after the drafts which the rosters were now set. If she's on this Friday, it will be 25 days since a normal TV appearance going back to September.
She appeared on the Oct 7th Raw. Running in to beat down Asuka & Kairi. Don't give you don't think that's a "regular" appearance but it is.
But it's only a week when you factor in the draft.
10/11 SD was the draft which she got drafted on-screen to Raw, so not surprising she didn't appear as they weren't going to set anything up on that episode other than Charlotte losing the belt to go to Raw.
10/14 Raw was the 2nd part of the draft and at that point they knew she was going to SD, so there was zero reason for her to be on
10/18 SD there was no need for her as they were setting up a filler defense for Bayley which Alexa rightfully shouldn't have been a part of that match because if she wasn't winning it then there was no need for her to be in it plus they can't really do a Alexa/Bayley title feud this soon as they just had a 2 month feud in the summer, it's probably gonna come after Survivor Series.
So he's right when he's says it's only been a week. New rosters weren't confirmed until 10/14 and Alexa wasn't officially SD until 10/15. So it's been 1 week when you look at that way.
