Real interesting what you mention about one of the members of the party train being IT savvy....been wondering how else DW could breach DNV's phone passcode....so there's a possibility perhaps....?
My posts end up being so darn long! I had this scenario to play out earlier but decided not to - such speculation...but think it's good to get braincells firing, and maybe someone has some 'aha' moment...
anway: totally speculative, not even MOO, just idea....
If leaving Dublin's - everyone's separating, headed to cars.....maybe someone dropped something in DNV drink, maybe she's just tipsy - she's celebrating, happy...maybe had one too many.....
Maybe other men at bar have noticed this....follow out to her car...but assume she is at least with DW from her own group (maybe others from party train too)
She's pretty out of it....one of these unknown men say something like "hey, we're headed to a party - you guys want to come along?"
DNV may be not quite right to drive, so going to call them 'perpetrators' say: 'don't worry honey, I can drive you - where's your keys? it's okay, get in...I'll take you."
Meanwhile said perpetrator's friend(s) drive his car, he drives DNV's, with her too drunk (or drugged) to drive...
DW is also going to join in
Maybe perpetrator is looking for her phone....he knows what he has planned...or she says 'oh no, where's my phone? I think it's at the parking lot..'
They pull into the Shell station...perpetrator gets DW to go back for it.....DW does and meanwhile doesn't like the whole vibe going on.....doesn't join party, doesn't go back to Shell station...
Meanwhile perpetrator and friend(s) disable her car - and drive off into the unknown...
Lots of holes in this story, lol. One being....these perps would know that DW knows....however could explain why DW is a bit squirrely about it all.....
Just ideas........
