Please Help !! Look at what Mercutio says to Romeo in Act 2, Scene 4, line 00, “now art thou Romeo.” What does he mean by this, and how should we interpret the line in light of similar ways that Romeo has described himself in the play so far?

the answer is emerged from.

orpheus descended to hades, the world of the death to rescue eurydice. no mortal had ever done this before him, he survived because he was protected by the gods. the word "underworld" gives us a clue, he emerged from it like a whale emerges form sea for exemple.
