Answer:
The consequence for this action that he doesn't mention is that the Prince has ordered for peace and if, now, Tybalt will create any havoc, he will be punished for it.
Explanation:
In Act 1, Scene 5, when Tybalt recognizes Romeo's voice, he immediately jumps to kill him but if stopped by his uncle Capulet. Capulet states that Romeo is behaving like a gentleman and so Tybalt should not harm Romeo. But the consequence that he does not mention to Tybalt is that the Prince has ordered for peace so any feud between them will cause harm to them only. Also, if Tybalt will fight Romeo, after the peace order, he will be punished for it.
