I submit that Snape probably cannot perform Expecto Patronus. It's

Potioncat:
Doesn't anyone think that the memory of Dumbledore agreeing to help 
him escape from the Dark Lord would be a happy one?  OR that the 
ability to say with conviction, "Dumbledore trusts me." would be a 
happy enough thought to bring up a patronus?
