I don't mind travelling together, but - I'm with one other person.

[ ...She's...not sure where Tsunade got to right now, but... ]

She's from the same place as me - Tsunade-sama. [ And in addition to being a Sannin, she's the current Hokage, apparently. And the world's greatest medinin, which is more to Rin's immediate iinterests. ] If you didn't mind the two of us, however...? I'm sure she'd be more than happy to accept your offer of help, as would I.
