Many, many, many, many centuries ago
Jessie was walking to store to get some food but bumped into Keres.

Jessie: Excuse me, I'm sorry.

Keres: WATCH IT, A$$HOLE! *punched her*

Jessie growled but on inside she was shocked.

Jessie: You ask for this!

Millions years later
Keres: You know I'm starting to like you.

Jessie: Me too.

Many more millions years later
Keres: Wanna be best friends?

Jessie: H*ll yeah! We should stop fighting or there will be no more macroverse or hyperverse.

Keres: Agree.
