I wasn't trying to write Morgan out of the story, Tom. Mainly, I was giving him a "temporary out" in terms of the storyline right now because I have a lot up in the air in RL at the moment. I figured that if I wrote it right, it would give me enough time to finish finding a job, figure out if I need to move, and get some other things settled down by the end of this month.
In story terms, I figured I could write him as, "He doesn't feel connected to the party yet, so he's wandering off, as he has a tendency to do when he's not comfortable somewhere."
My apologies if it seemed like I was trying to end his adventures with the party before they began.
Alina gave me a great opening to come back with the neglected backpack. Once Morgan's emotions have stopped clouding his vision long enough for him to see straight, he'll realize the pack was left behind and come back before the party leaves.
