You lost and you ran away here, didn't you.

Geez, you really never learn...

Ugh...

What, why?

Not at all.

Ugh...why...?

Go home, already.

I don't want to be involved in your quarrel between sisters.

No...I can't...

I've used all my magic power during this last battle...In this situation, stepping into the Priestess' sanctuary it would be a suicide...

In short, your sister's still upset, you're scared and you don't want to go home.
