That one ask where Crepus finds baby Kaeya
I imagine baby's in one of those wicker baskets for babies and a note saying give him the love their homeland couldn't, to let him be able to dream, that they couldn't go through with the plan their superiors had for this baby bc he's just a baby. They put his birthday and potential names they had thought of, there's fresh bloodstains on the note and welp there's a faint blood trail further away from the house, darling is the one who tracks the body down and uses their dendro to cover the body up since this is the least they can do.
Baby Diluc absolutely crawls into the basket with Kaeya and is gonna give crying Kaeya his teddy bear which is a big thing bc he loves that bear
Now, I'm just picturing Reader going back into 'Fatui Mode', so to speak. While Crepus is fussing over the abandoned baby, and simultaneously trying to calm Diluc down, the Reader notices the bloodstains, and it doesn't take them long to conclude that something terrible has happened or is going to happen. They grab their Catalyst and they're already bolting for the door, telling Crepus to stay inside where it's safer.
Only once they've made sure that the house is secure (and is convinced that their family is safe, it's not a trick of the Fatui), only then does that distant, icy look in their eyes receed. They don't tell Crepus about the body they've covered with plants. They just tell Crepus to get some sleep, they'll take care of the new baby, and they can talk about things in the morning.
The Reader ends up staying awake the whole night, alternating between pacing the room, still cautious and wary of a possible attack, and rocking a fretful baby in their arms.
