Does this seem odd?

Her time will come. She's been in almost all the episodes in season 2; but you're right, she hasn't been the focus. But then consider this: we notice these things when following the show weekly, more drawn out. Season 1 is easy to approve and get used to, since one can watch all the episodes in a day.
I'm guessing she'll come up soon. There's that "Smile" song, right? (I haven't listened to it for sake of spoilers.)
