I want to take Yoshimo with me to Spellhold even though to this point I dumped him after escaping Irenicus' underground prison in the very beggining. I haven't initiated anything with the shadow theives even though they are the group I will chose. Here's the question, do I need to take Yoshimo through all of the Shadow Theif stuff for his part to play out correctly or can I just grab him right before I get on the boat?
