In the above passage, Shakespeare captures the dedication Mercutio feels for Romeo. Mercutio's aggression towards Tybalt demonstrates the rage he feels when Romeo is insulted. Shakespeare emphasises Mercutio's sense of disgust when he exclaims 'O calm dishonourable, vile submission!' in response to Romeo's calmness. The use of 'vile' demonstrates how passionate Mercutio is in his defence of Romeo's honour. Mercutio fears his beloved friend appearing weak.
