It is in the quest notes. And all of this was after the faction swap. So what does this all mean in a practical sense? Is there a way to reload him?
There may be. First save your game in case you need to go back.
1. Go into "Configuration" before you start the game. Click the boxes for enable 'Cheat Mode' and 'Edit Mode.' Best also to use 'Start Windowed' too.
2. Start the game and hit <Ctrl> plus <~> at same time a text box will open. Type "cheatmode."
3. Go to Camp, go to "CHEAT MENU!" click on "Update political notes" & "Update troop notes."
4. Hit <Ctrl> plus <T>, this will let you see all of the map.
5a. Open Notes and go to Characters and find the sister & brother. Check to see where they are & what faction they belong to. If it does not say (Report is current) it means he or she is not currently on the map.
6a. If you found out where she was go there (You can hold <Ctrl> and mouse click in open spot next to Town or Castle to teleport there). Check to see if you can visit her. If not go to 'Castle' and debug notes should run telling you if she is there but you are not allowed to see her.
6b. If it was not current, go to someone in his current faction and ask where the brother and sister are. (1) If they say they do not know where brother is, he has not respawned yet, think only other possibility is he is in prison or being carried by a enemy lord as a prisoner. (If you found out he was in prison you can break him out, or if captured defeat lord & release him - under certain circumstances the sister will not respawn until her brother does.) (2) If they do not know where sister, you will have to wait for her to respawn.
7. If you need her to respawn you can return to the Cheat Menu and use "Infinite Camp" to speed through time. (best to make a separate save game here just in case). Just click on map to stop time. Repeat steps 3, 4 & 5 until you get "Report is current," then retry step 6 for him or her.
Hope it works.
