as if have seen/had seen

[subhajit123]

What's the difference between these two sentences?
1- He looks as if he had seen a vampire.
2- He looks as if he has seen a ghost.

 

[tedmc]

There is no reason to use the past perfect tense in the first sentence.

 

[Roman55]

Apart from the problem with the tense in #1, the difference is that #2 is an understandable and existing expression whereas #1 isn't.


#1 assumes that we all know what people look like when they see a vampire, and that they all have the same look. I don't.

If you want to ask about a difference, the rest of the sentence should remain the same. Changing anything that isn't the issue at hand just complicates your question.
