Something me n' Cat came up with once upon a time...Spica runs into Kiona on her way to Nome or something.
Spica tells Kiona how she is on the way to Nome (probably needs directions) and how she wants to be a sled dog.
Kiona is probably inquiring from what height Aleu dropped her on her head.
...Or informing/warning her that being a dog isn't all it's cracked up to be.
I can't imagine what Kiona might see in Spica that she would bother talking with her. Oh and Spica technically has more wolf in her than Kiona- which is why she's about Kiona's size.
