Firstly, inspect the ship to see if it has helpful supplies, be it rations, tools for the maintenance of the ship, equipment that could help you get a better knowledge of your bearings or, most importantly, a means of communication. Ships usually have radios or transmitters, right?

However, if any food is found, maybe you should refrain from eating some right away. You don't know if you can eat the same food as a literal alien being, and even if you can, you don't know if they would be happy if they found out that you ate their food and drank their water without permission. You already did one of those things, doing the other may be pushing it a bit. Avoiding conflict would be the best for both of you.

Secondly, if the cargo bay has enough space for you and the pilot, have Dee Dee just outside the ship's entrance. Being a robot, they should do just fine exposed to the elements as long the weather is relatively nice. If anything, being placed just at the door will allow both of you to quickly reach each other if anything happens.

Also, if the pilot happens to wake up while you are sleeping, it would be rather useful to have a very logical synthetic individual being there for squash any misunderstandings.

Misunderstandings are quite easy to happen when you wake up confused, hurt and surrounded by strange people, after all.
