its the 2nd dialougue triggered with Imoen saying she were wondering whether the PC would come and saver her or not, admitting that she had doubted her; the mod i installed were listed above and it triggered after i finished the Nakshel Mine quest, although i did make the PC talk to her once at first when i was outside of Candlekeep, where i said she wasnt talking too much.... and then she gained 350000exp... i had to use Shadow Keeper to fix that
also, since i am clueless to any modding, coding, or the like, so im only mildy decent at Shadow Keeper
