Eien seemed intent on licking the face of who she thought was Kushina, apparently blissfully unaware of any strange scents her chakra might have been giving off (but then, given the size of Eien's teeny tiny nose, perhaps she hadn't picked up on it yet, or perhaps she was just too excited by physical attention to care about a silly difference in scent. How could anyone resist that level of adorable?)

Kakashi arranged the characters in his most readable chicken-scratch of untidily aligned strokes - apparently all the time the academy sensei had spent recently trying to shift his handwriting toward legible hadn't stuck so well - and once he'd finished, he thumbed the scroll, chakra sealed the exterior and knelt to hand it to the expectant canine at his feet, who promptly took off like a bullet; gone in a small plume of dirt.

"He's good with names, it'll be right with her." He held out a hand to take the dog from not-Kushina's person.
