10.31.2287 - Halloween 🎃 Although nobody celebrates costumes and candy anymore in Concorde, or anywhere else Jenn is aware of. She only knows the date because her Pip Girl® tells her so.
...and she spends this formerly festive day running atop the Museum of History, trying her best; taking .308 potshots at the giant deathclaw running amok on the streets of Concorde below, while Preston Garvey, on the balcony below the roof, also takes shots with some sort of energy weapon. Jenn X remembers this little town the way it once was: full of pleasant small shops she could drive to, just down the road from her former neighborhood.

Maybe grab a burger and strawberry milkshake with one of her girlfriends before heading home. She keeps getting flashbacks of memories from her old life, remembering her favorite florist shop and so on, fluorescent lighting, some neon lights for the little corner pub; the very worst thing which she remembers occurring was a fender-bender between a Chryslus and a Ford Kinto (the latter owned by one of her son's teachers). She'd never expected the sounds of gunshots and ricochets would ever reverberate the walls and avenues of this tolerant, quaint little New England burg.

...and that SHE and a complete stranger would be causing such mayhem.
...now Concorde is strewn with corpses! Trash and rubble on the streets and in those formerly pleasant establishments. Rusty, ancient vehicles (one of which she and Garvey were able to explode from a safe distance, though this didn't slow the f---king deathclaw at all, even as the Corvega disintigrated right beside the monster.)w
Jenny's got a gun. A new gun, that is: a rifle with a bayonet attached. In previous days, she backtracked to Vault 111 and numerous other locations, looking for fusion cores so she can continue to walk her new power armor all across the map. Wasn't able to find any cores but she finally got this half-decent rifle, which is better for long-range action than her shotgun or pistols.
....but the deathclaw persists on the streets below. Worse, it's learned how to hide its massive self behind buildings and other large objects.
Jenn overheard the red-eyed woman from Boston talking to some Concorde survivors holed up in the museum about her plans to defeat a second deathie; oddly her idea seemed to be to face the damn things head-on, somehow.
