They didn't start out as friends when they first met almost 4 years ago.
In fact they butted heads frequently and it wasn't pretty.
Thankfully that phase is over and these two can't seem to get enough time together.
When they play, Will is Batman and Cruz is Green Lantern.
They have boundless energy combined with zero attention span.
They're fun to photograph because they laugh a lot and make sound effects.
It's all six year old boy stuff!
