Lost contract to very junior in-house hire. Now being asked to train them?

[silverlight1]

You should look at this as Knowledge Transfer which is a standard deliverable for any project.

Set out clearly what is being transferred and have the recipient sign-off once complete on what has been transferred.

Say you are available on a retainer basis post the KT

Likelihood is that Junior newby will leave and you can then setup a proper support contract or increase the retainer.

You are sharper than the client but they don't know this.

When they come back to you desperate for help you can name your price.

A couple of these types of contracts paid for an upgraded 911!

This is exactly the approach to take (unless the OP doesn't want to!)

The newbie may not leave and need ongoing support, QA etc.
