Etho is apparently notorious for building his interiors first and building exteriors around them. But I don't think he's even visited his base since Decked Out started!

I missed a lot of what went on at the beginning of the series - I only have a couple of people watched straight through S9 - but I started watching everybody a couple months before DO2 (I am no longer doing this because whew) so I got a good idea of most of the bases, except Iskall's which I know nothing about. They are all very cool!
