Why? You still haven't explained why you think Courtney is a companion. Travelling in the TARDIS is not enough.

And it certainly doesn't matter whether they were taken reluctantly or stole the TARDIS. Leela, Frobisher, Adric; the list of dubious entries goes on. Turlough spends his morally grey moments trying to kill the Doctor. All that is irrelevant. What matters is if they're fulfilling that companion role, and I don't think Courtney does.
