Out of context Rabbot (or not?):
Jack has a single postcard stood on the edge of their shared workstation. It's the only personal touch of Jack.
The postcard's old, faded pink lake under a washed-out blue sky, somewhere vaguely exotic. The corners are worn, scratched, smudged with mysterious oil stains that no one's dared investigate. It's been sitting there for years, mostly ignored.
Dana once joked about it during a handover a long time ago. Jack, polite but unmistakably serious, replied that the postcard was very important to him and anyone who messed with it would answer to him personally. Robby, for his part, had tried (gently, awkwardly) to talk Jack out of keeping it there. Said it was too easy to get damaged or lost. Jack just gave him a look and said, "It stays."
It sat there, forgotten again, until one day an intern's hand slipped and sent their 2L water bottle crashing across the station. Dana jumped in to the rescue while the intern scrambled to save the PC. She did her best to save the personal items: Jake's sketch of Robby and the ED staff, a photo of Dana, Robby, and Jack with Monty, a few stickers and scribbled notes.
And Dana managed to save the postcard.
That's when she saw the back.
Sent to Afghanistan. Recipient: Jack. No return address. Just one line, written in faded but unmistakable familiar handwriting:
"Watch over yourself, take care of your body, your soul if you can."
