I can only repeat what's been said already...EPIC beard, man!

As it stands, your beard definitely looks well-kept and established, so any ideas of laziness or pranks are too far out to even count on. I think keeping the stragglers at bay with reeeaaally conservative trimming will help it stay well in hand.

I had the same struggle with my 'stache as well. It doesn't connect too much on its own, but I grew it out some, I am able to blend it over the "bald spot". Hang tight and the will definitely follow. It looks like you are already training it to the sides which is how to keep it out of your mouth while eating and talking and to help it join up to the rest of the amazing beard you have going.

Keep at it!
