Naruto and I arrived shortly after one another, and have been travelling together since. [He's been filling your role in your absence, Sakura. Would you like him to relinquish it to you, or are they going to share Naruto-sitting duty?] We split up from the others two weeks ago.

[More like they were left behind... plus there was Yumi to look after. Large groups are dynamic and changing and there was no question that Sasuke would go after Itachi.]
