Which lines in this excerpt from act v of shakespeare’s romeo and juliet create dramatic irony ?

Dramatic irony is when the reader knows something that the charictors are not aware of.. so in scene V it would be the fact that we know juliet is trying to fake her death so that her and romeo can live together but, we also know that romeo never got the letter saying that... (so the dramatic irony is that we know that romeo is unaware that the death is a hoax but none of the charictores are.)
