OMG: Dumbledore's trust!

It just hit me.

Snape interviewed for a job at Hogwarts at the same time as Trewlawny,
that's when he heard the first part of the prophecy. He then started
at Hogwarts in September 1980, a couple of months after Harry was
born. At this time he was a loyal DE, the Potters were in hiding and
it pretty much stayed that way for a year. A week before they were
killed, the Potters went under the protection of the Fidelius charm we
know this from Fudge talking to Rosmerta, et al in PoA. This has
always been a worry, why did they wait a year? Ok so far.

in HBP, Dumbledore tells Harry that Snape was full of remorse when he
realised how LV had "interpreted the prophecy", later on, Harry tells
everyone:

"Snape passed Voldemort the information that made Voldemort hunt down
my mum and dad. Then Snape told Dumbledore he hadn't realized what he
was doing, he was really sorry he'd done it, sorry that they were dead."

But this isn't anywhere near what DD had told Harry. Harry is reading
between the lines.

What if the reason DD trusts Snape is that Snape came to him before
the Potters were killed, telling him of what LV planned to do and that
it was this that prompted Dumbledore to put in place the Fidelius
Charm? Snape wasn't to know that the charm would be useless because of
Wormtail's betrayal.

There is a but though, would Snape have known that Wormtail was a DE?
and if he had, would he have revlealed this to DD when he told him of
LV's plans? There was probably no love lost between Wormtail and
Snape, so they may not have been aware of each others loyalties.
