Batman - All Media Types+1

Friends vs. Cubicles

by SunnyBlue

Damian is stuck patrolling in Metropolis with Jon, bored out of his mind because nothing ever happens here and there's so much going on in Gotham that's actually important. So maybe he's being a little meaner than usual; it's not a big deal.That is, it's not a big deal until he investigates a building and ditches Jon outside, and hears something he wishes he'd never had to: a ragged scream in an all-too-familiar voice.

are you visible today?

by sinceritiies

“Do you own Groundhog Day? And if you do, can I borrow it?” Clark glanced around the room, his eyes wide and panicked behind his glasses, before turning back to Lois. He leaned in and lowered his voice. “Are you in it, too?”   Or, Lois finds herself reliving the same torturous Friday for seemingly no reason. Clark might be her only hope of getting out.

Shades of Accuracy

by Maelstrom_Breaker

Things are getting better. Clark's moved on from his break-up with Lois while still being friends and protecting Metropolis. Jasmine has gotten... better. Things are more stable in Park Row, she's keeping her distance from the Bats, and her gig as Superman's ally Red X has been going well enough. Things are good. Now, if only people would stop looking at them doing better and think they're dating! It's not like that! There's no way they like them like that! ... Right? or; Five times someone thinks Clark Kent and Jasmine Todd are dating, and one time they actually are.
