About Sime Romance Options

[christophe]

Dear Vlad & Senka, I've some questions about the Sime romance in TS mod. But before, a precision: is it possible at the installation to exchange the BaldurDash 1.68 for the BG2 Fixpack 10 without creating issues ?
BEWARE - SPOILERS:
1) Will the romance be activated through the whole game (SoA + ToB) without Kachiko & Yoshimo (for example by expelling once for all both NPCs at the beginning of Chapter 2)?
2) Is it essential to go to the Cursed island and make the quests here ?
3) When - and how - intervene the fight against the chromatic dragon ? At the Chapter 6 ? Will the team be teleported and how they return after in Amn ?

I hope you'll give me a quick response; and sorry for my poor English, it's not my mother tongue...
