1 Iki Piki: Bye Spanners. Serron and I are going to deliver the organs to the black marketeer who our past selves will later steal them from.

4 Spanners: Yes, but look what happened last time!
4 Iki Piki: Fair point.

It makes sense. If you get to go back and redo something, you should probably try it a different way to see what else could happen. Unless you care about maintaining causality or your own existence or the fabric of reality itself, or some such unimportant stuff.
