That damn blood protection thing

[fishinginthemud.livejournal.com]

My sincere apologies if this has been addressed before, but I haven't found anything on it yet.

We are told that Harry survives the Killing Curse from Voldemort because Voldemort is now a "blood relative" and Harry can't be harmed in the presence of his "blood relatives." But at that point, hasn't the "blood protection" spell already ended, since Harry is now 17 and no longer lives with the Dursleys? Have I missed something?

I just assumed Harry was in shock and psychosomatically paralysed for a while. But yes - this is definitely a contradiction, unless there's some bit of magical theory that Harry didn't pay attention to defining which spells hang around and which don't. (Or, as you say, that Snape knew Harry might be there and released him non-verbally).
