In Act 1, scene i, Benvolio gets in the last words:
ROMEO: Where I may read who pass'd that passing fair? Farewell: thou canst not teach me to forget.
BENVOLIO: I'll pay that doctrine, or else die in debt.
Benvolio is trying to convince Romeo that it is time to check out all the other fish in the sea. Romeo doesn't think he could possibly forget Rosaline. He is too taken with her, so Benvolio commits to take whatever time it takes to get Romeo over this girl who doesn't want to have anything to do with him.
In scene ii, Romeo gets the last words, but only after Benvolio convinces him to go to a party to check out other ladies. Romeo's words prove he only wants to go in case he might get to see a glimpse of Rosaline who is indeed on the list of the invited:
Tut, you saw her fair, none else being by,
Herself poised with herself in either eye:
But in that crystal scales let there be weigh'd
Your lady's love against some other maid
That I will show you shining at this feast,
And she shall scant show well that now shows best.
I'll go along, no such sight to be shown,
But to rejoice in splendor of mine own.
These scenes end with the same characters discussing the same topics and each character has maintained their same motivations.
