^ By this I mean that Blaze was likely to have not already known Sonic, if this is what the writers originally intended.

With that out of the way, I don't think that Blaze already knew about Mephiles- otherwise she obviously would have warned Silver about him when he started to belive him. (Did she warn him at some point? I didn't play that entire game.)

I think that she was unsure about what Mephiles had told them, not knowing whether or not to trust him. But at the same time she wasn't sure if she had the option of standing against Silver on his desire to kill Sonic, considering that this was the only information they had been given about potentially changing their time in the future for the better. So maybe she decided to take this chance for the time being, but while in the past she took the chance to try to find out more about what could have caused their future?

This is my opinion on it. I think it sounds like a reasonable explanation for her behavoir. The again, it seems likely that the story writers got lost at some point with this game.
