1 Iki Piki: So what's your plan to get out of here?
2 {Iki Piki 2 and Serron 2 look at each other}
3 Iki Piki: You have a plan, right? You know how we escape...
4 Serron 2: How did we get out of this?
4 Iki Piki 2: I told you we should have written it down!

Time travel stories are full of odd causality thingies.

Iki Piki is assuming that the fact that his and Serron's future selves clearly exist means that they must somehow get out of their current life-threatening predicament.

He hasn't reckoned with their ability to screw things up.

Don't do it! You'll most probably end up erasing yourself from existence.
