I'm very probably getting my timelines confused. But to me if the Hartonin didn't go on and get caught in the time loop then their ship wouldn't be stuck in it when Mike & co arrived.
I have another less classical suggestion.
Seeing that Mike is from Australia and Pacha resembles a koala, how about 'The Boomerangs'? After all, they do keep going off to far flung places and keep coming back!
While I like the 'Booneiverse' @drpaladin, I'm not so sure about the Boonettes. That makes them sound too much like the male equivalent of the Ronettes from the 60s!
So, what has seemed inevitable has finally happened. The pair have made the logical decision to go their separate ways into the future, but will some stroke of chance bring them back together??
