"Take the Kage, TO WHERE I AM..."
The manga above shows Tsunade talking to her summon while she is impaled by Mokuton. She says something very interesting to her summon. She refuses to let it heal her body by sticking it back together. But more importantly, she tells the summon that she can still save the Kage if it brings the bodies to WHERE SHE IS.
This is very interesting. Tsunade purposely does NOT say, "bring their bodies to me" but she says "take the Kage to WHERE I AM"... alluding to the fact that the "real" Tsunade is in another location.
Your ideas on her choice of words?
THEORY: This is a shadow introduction before showing Tsunade's Senjutsu Powers (same way Orochimaru alludes to having Senjutsu) soon to be illustrated...
