I don't dispute that she was a companion within certain segments of Stolen Earth/Journey's End. My distinction is more subtle, that there are multiple "adventures" within the span of Stolen Earth/Journey's End and only one story. She was not a companion throughout the entire story or even most of it, but she was a companion throughout some of the adventures.
DiSoRiEnTeD1, given that you yourself used the phrase "it was a short adventure", rather than "it was a short story", I rather think we're done here. Her actions in Stolen Earth/Journey's End are sufficient to make her a multi adventure companion, not a multi story companion.
That said, thinking about the Kazran example, I guess only the "he was a companion of Sarah Jane and not vice versa" angle would work.
