Answer:
Mercutio develops the theme "it can be difficult to follow forbidden love" when it comes into conflict with J *'s first.
Explanation:
As you may already know, J *'s cousin starts to start a conflict with Romeo because of the enmity between their families. This enmity makes the love between Romeu and J * forbidden, but Romeu is already married to J * and does not want to fight with her cousin, because she sees him as family. However, J *'s cousin's taunts become increasingly violent, causing Mercutio to attack and die.
Mercutio's death establishes the theme "it can be difficult to follow forbidden love", as it shows that forbidden love, however strong it may be, will cause painful, violent and difficult situations to endure.
