Oh man, this one time...
This one time I built my fortress out on a haunted lake; a constructed tower. To start off I only had one militia dwarf, a woman. Naturally, she immigrated to the fortress married, and gave birth during training. Dumbie just picked up her kid and went right back to swinging her copper mace at the air.
A year later, she's still the only militia dwarf. And out on the bridge; a thief! Protect the horde from the skulking filth! I sent her out to take the little asshole out (I had been having a recent string of stolen children, I don't even know how). She strikes it at, it counterattacks. She dodges, and drops into the lake. Drops her kid in the lake, gets out and clobbers the kobold. Being a haunted lake, I order the kobold dumped into the non-haunted part of my base. She goes right back to training.
Dwarven baby has drowned. Oops.
So yeah, she was a little depressed. I was fine with that; one step closer to not caring about anything any more. 'Has lost a child to tragedy recently'. I couldn't fish it out of the lake. 'Has had to put up the miasma of a child recently'. Had to take her off the training regiment and into party mode just to get her out of miserable status.
A while later, zombie baby comes out of the lake. Ha! Now she has to go kill her zombie child. Then dump it in the incineration pit. Looking through her thoughts, 'Has been attacked by the undead lately'.
Later, her child comes up as a ghost. Not violent, thank god, but still haunting its mum. Couldn't slab the little shit either, due to glitch. So now, after dropping her baby in the lake, drowning it, being plagued by the stench of it, being attacked by its zombie, then haunted by its ghost, she goes insane. Babbling, goes and starves to death. Ha ha ha.
