"You want to come along while I fix the ozone layer? This is likely to be boring except for the part where it involves being in a spaceship. I could also drop you off at home on the way."
"Well - was there also something we were going to talk about while we're not on the same continent as Rayne and he probably can't hear us?"

Ripper does not have wings of his own - or a tail - but he manages pretty well with his available limbs.
