I follow that reasoning too. If it's stated in canon, then, there's no reason to believe otherwise. However, off-screen speculation is good too when it's properly hinted in and outside of the show. Another example would be JNPR finding out about Blake's heritage. It's stated in the commentaries that Blake herself agreed to telling them which shows just how much time the two teams spend together off-screen. We've never seen her talk to any of the members of JNPR but she apparently trusts them as much as her own team and that assumption is properly backed up by that comment on the DVD.

As for your question, it's not clarified but from what we can see Weiss showed surprise when Blake facepalmed because she knew what was coming. It suggests that she didn't know.
