There are several ways you could attack that one. (common event that tracks event1's position & moves event2 in that direction, a pathfinding script, a script to implement a "Move Toward / Approach Event" movement command, or just choreographing your scene if it's a cutscene.)
Can you explain what it is your are trying to achieve in the game? Rather than ask how to implement a technical solution, state the problem in non-technical terms. e.g. "I'm making a cutscene, and I need the squire to follow the knight when he moves around."
It would be much easier to recommend the appropriate solution if we understand what it is you're trying to do.
