Maybe with that new Benny character, that will most likely be the monster Dean finds, we can get some development.

I'm afraid Amelia will just bring the old short-lived romance where they have to part ways or she ends up being a victim and dying or rejecting the hunters. not very interesting after 9,000 times. But I have faith in that new monster character for Dean.

And hopefully the brothers can get to talk a bit, talking would bring character development too.
