About first question, no idea. I gonna answer you about the "applymovement". If i have understood well, you want to move a person and he/she stay forever in the B position, right? Try this: put on your map the same person on twice positions. On last position must be hidden, and the first shown. Assign different flags in both person. During the script, set the first person flag and clear the last one.

I hope help you.
