So i looked up these quests(i didnt remember them by name). The quest Good Intentions ends with you talking to the npc(Ilberd) who starts the following quest. So you would have literally been standing in front of him ready to talk to him again to start the following quest. Now if what youre saying is he never appeared in ET to begin with, then you may have skipped a step in the previous quest where you talk to someone in mor dhona(the one who told you to meet with Ilberd).
