Cue Points and More

I have attached 2 ZIPs with the files to view.
I am using Laco’s Tweens 1.20 in this.

I have made it react to the cue points.
But what if I wanted to have the 2nd box move at the same time as the first?
Or what if I wanted to have all 3 boxes fade out when the audio ended?

I cannot figure out how to make more than one MC react to a cue point.

Ideas? TIA.
