Bastion's deep voiced narrator Rucks is a serious guy, full of insight and detailed information to help the Kid rebuild his world. Turns out he's not the only technological maverick in this universe.

In this video Rucks gives an account of his history with Aperture Science founder and lemon enthusiast Cave Johnson. At least their hypothetical history. This isn't the first time Bastion and Portal 2 have crossed paths. Judging by the awesome level of the first two crossovers, let's hope it's not the last.
