I just got to Laverre city a short while ago, and I met the Team Flare guy who offers to let you join Team Flare for 5,000,000 shekels.

I've searched the internet fruitlessly to see what happens if you pay him, but I haven't found anything. I'm stopping to ask here as a last resort before I farm up enough shekels to pay him, since it's not really that hard, just tedious.

tl;dr: What does paying the 5 million to join Team Flare in Laverre City do?
