As to this, it's not like nothing occurred... because auntie SS relayed her text from Tylee as coming in full sentences and words, with no text-speak.
This is, IMO, because SS had plenty of time to study and absorb the friend who I think is one and the same, who said "Tylee never used text-speak", with the ["so in retrospect I realized it was Lori texting me pretending to be Tylee"] unspoken.
Summer wanted to remove any doubt that she had texted with Tylee directly; whether it was true or a lie (for the record, I think it is a lie).
IMO, MOO, JMO
I thought MG said at some point that she was out of town for Thanksgiving? I could be wrong... a lot of intel floating around up in my brain these days. If she was out of town she may not have wanted to opine about things happening "in town", without being there firsthand.
I mention this only because I've seen quite a few people critical of her failure to report things earlier.
