I don’t think the pinned tweet being re-discussed is relevant, although it is ironic given what’s happened.
In the Brian Shaffer case, he disappeared in 2006 and has never been found. He was last seen on April Fool’s Day and has the tattoo of the cover of a music album titled ALIVE on his arm. MT’s tweet strikes me similarly.
Is it possible that 1 day we will learn Mollie (or Brian above) disappeared willingly and she chose the pinned tweet (or he chose the April Fool’s date) as a little tongue in cheek joke on their way out? Well sure, in the absence of any evidence about where they went so far, we have to acknowledge it’s possible.
But I think, until anyone tells us otherwise, LE and anyone else working on the case (including us) should treat their disappearance as serious, and assume they may be in desperate need of help... Especially since both of these individuals had a lot going for them and didn’t have a track record of doing irresponsible things.
If you want a mystery, in your down time, feel free to drop by Brian’s thread too. Trying to keep it alive over there.
