Fearful Child

Jim Kirk gets shot by an automated weapon while on an away misson. Instead of injuring or killing him, it deages him.

Now Spock and McCoy have to try and fix it, all while caring for 4 year old Jim. This is made harder by the fact that he is terrified of everyone but Spock.

The more they watch and listen, the more Spock and McCoy want to find Winona Kirk and make her just as afraid as she has made her son.

There is a brief nudity scene in the last chapter. All characters involved in said scene are adults. There are some sexual terms used. However, I do not believe it is enough to change the rating to mature.
