You have to wonder what Peter has been up to for nearly a year after
the scene at Spinner's End.  Making himself at home in Snape's house?
 Drinking his elf made wine?  Reading his books? (Probably not.)  We
never hear another word about Pettigrew.

I think it is likely that Wormtail will switch sides one more time.
And who better to work on his self interest and fear of Voldemort, and
eventually turn his coat for him, than his unwilling host.  Perhaps it
has already happened.
