I am serching for two Kim/Tommy fics.

The first one I don't remember much of except it starts with Kim piloting a zord through an asteroid field.

The second one I remember more of, Kim and Tommy are back together but the other rangers don't know it yet and kim is living in San Francisco and Tommy is living in Reefside. At some point in the story Kim is moving in with Tommy and she finds a baby girl left on her doorstep in san francisco. They adopt the baby girl and name her Ariel I think.
