Potioncat:
The other explanation would be that Snape just happened to come out of
DD's office at that moment and quickly thought to himself, "I think
I'll tease Potter."  And then DD just happened to come out a few
moments later.

JKR has placed Snape there for a reason, and set up tension for the
reader.

Potioncat:
I mean, that Snape beckons Harry to him at the entrance. Snape is
calling Harry back to the doorway. He makes unpleasant conversation
until DD arrives. Why torment a student right at the headmaster's
office, unless you know the headmaster is coming to see the student.
You'd think if Snape was only out to hassle Harry, he would have
directed him away from DD.

Snape is not restraining Harry, Snape is detaining Harry. If a teacher
says come here, the student has to come.

Potioncat:
Well, he didn't say I have to go somewhere, he said, I have to see DD.
And Snape kept him there until DD arrived. 
 
I don't recall which chapter it will be in, but let's look at this
again when you get to the part where DD and Harry are watching Snape
say his mark is darker. I think the canon supports my view.

I know we're not suppose to write "me too" posts, but just for the
heck of it, what do others think? Does this hold up or is it come
across as mere speculation?
