What happens at Spellhold if you leave Yoshimo behind?

Yoshimo is magically compelled to betray you to Irenicus at Spellhold but- if you either don't include him in your party or dismiss him before going to Spellhold, how does your encounter with Irenicus when he does away with his disguise as a doctor then admits to planting Yoshimo with you end?
Best Answer
The confrontation with Irenicus at Spellhold ends when...
Irenicus flees, leaving you to face another group of "murderers".
If Yoshimo was in your party and compelled to betray you, then he enters the scene after this and...
...attacks you. When you defeat him, you can take his heart to undo the Geas on Yoshimo, starting a quest to reconcile him with his god Ilmater and give him peace in death.
If Yoshimo was not in your party when you went to Spellhold...
...he will not be there to challenge you, leaving you free to escape.
In this case, then if you encounter him later on...
...he will immediately die because of his Geas. In this case, there's no option of reconciling Yoshimo with Ilmater since he drops no heart.

Can you save Yoshimo?
Leave him inside a inn or something (inside Brynnlaw, I presume), and go to Spellhold. After that, invite him back to the party and he dies from the geas. Now you can go ressurect him at a temple and he's back!Where does Yoshimo go?
Yoshimo goes to the copper coronet, when removed from party. > He stands at the end of the table right near the entrance way.Baldur's Gate II: Enhanced Edition [Part 85] - Spellhold
