*spoiler* Therella's missing son?

This was one of the quests I picked up *after* I cleared Durlags Tower.
Honestly I can't be bothered going all the way back there...

I don't remember finding a corpse or speaking to an NPC that is her son.

Did I miss out on much?

Or alternativley could use the old trustworthy CHEAT if need be....whats the code for it?
