Show layer when timeline starts, Hide when revisiting?

I have a drag and drop where I wanted to instructions to be on a pop up before the exercise begins. 

I have it set up to show layer when timeline begins. The only problem is that if you go forward in the course and then return to this slide, you have to view the instructions again. I don't want the student to have to click through the instructions again to review their completed drag and drop.

Is there a better way to do this (I am horrible with variables...so I'm sure there's something to be had there, I am just clueless on the possible execution). 

Any help would be appreciated! Thanks
