About that...what is Klaus' opinion of the Heterodyne Boys right now? Obviously he worked with them before his enforced trip to Skifander, but when he got back he found Europa in chaos and the Boys gone. Not only had they apparently abandoned the place, but later on he found they'd left a powerful female Spark hidden away to really put the cat among the pigeons. I would be entirely fine with Klaus coming to the conclusion that the "good" Heterodyne Boys was all an act to lull everyone into a false sense of security before they could revert to type and start sowing chaos.
