Thestrals again.

No: HPFGUIDX 71374

I found an interesting plothole, and I don't know if thats been 
taking care of in reprintings or not.

In OOtP, Harry sees the Thestrals for the first time, after seeing 
Cedric killed. Of course, nobody else can see them, and this is the 
first time Harry has seen them.

At the end of GoF, Harry is told to wait for the carriages. There's 
no sign that he sees the thestrals, but HE is the one watching out 
for the carriages.

Did he have too much on his mind then, and simply didn't notice the 
Thestrals at the end of term? Or is there a time period after seeing 
somebody die before being able to see the Thestrals? It was a 
plothole occurred to me, but maybe he was just thinking too much 
about going to Pivet Drive to notice them, because it was after 
Cedric died so he should have seen them.

Thoughts?
