Coolio. I like the idea of characters that might know someone but not actually know them while the other might have no idea who they are at all. 

Not sure I'd go that route with Andrew, I have no idea how much time he'd spend on youtube or what he'd be looking at in general on there, stuff to think about! Janelle might have pointed him out as having a few good educational videos, but he might well never have looked at them. 

I also hope you are aware that your signature is oddly hypnotizing. I think it's that eye flutter, it just drags the attention away from everything else... o.o
