Can somebody explain this to me?

Hey, guys, I wasn't really sure if it was worthy enough to be discussed, but I was reading on the Zira article on The Lion King Wiki, and one of the users there managed to contact Darrell Rooney (director of TLKII) via Facebook earlier this month about whether Zira is Scar's mate or not. His comment is listed below:

He's confirmed by stating that "her (Zira) relationship with Scar became obscured".
According to Merriam-Webster, the word, obscured, means, "not clearly seen or easily distinguished", while other definitions state "dim, dark, gloomy".
First off, how can a relationship be described as "not clearly seen"?
I would have appreciated if he used the word, "changed".
Second, he also added that Kovu was described as an orphan if he can remember correctly. He didn't evaluate on this, but Zira is said to Kovu's mother as stated in the film.
So, Rooney's statements are really confusing; well at least to me so can somebody explain this to me?
