Snape hearing Malfoy's name in the Hospital (GoF)

I was rereading GoF and noticed that in the hospital scene Harry 
starts shouting names out at Fudge at who was at the graveyard.  
The first name he mentions is Lucius Malfoy and Snape looks quickly 
at Harry, and then quickly looks away.

I found this to be a clue, but as to what, I am uncertain.

My theory is, as of last night, but it could change, that Snape 
trusted Malfoy, which is why he likes his son, and Snape was actually 
shocked to hear that bit of information.

It could also be that Snape just didn't want Harry blabbing names 
when he knew the kind of trouble it could cause.

Anybody else have any theories?
