Eddie:
On face value, Harry could have learned that ultimately he will have a
difficult time against Voldemort if he doesn't learn non-verbal
spell-casting and occlumency.  More subtly, that Snape is first and
foremost his teacher and his ally.  After all, during Snape's
farewell, he had nothing to lose in capturing Harry and taking him to
Voldemort.  Previously, Snape clearly told Bellatrix that the only
reason he never took Harry to Voldemort -- or killed him -- was
because he (Snape) was trying to maintain his cover story.  Well, the
killing of Dumbledore pretty much ended that.

IMHO.
