Pen in Hoof (Not)

Twilight and Rainbow Dash have a very sane, very calm discussion about quills and pens. Yes, very sane, very calm, and very controlled, just like two normal mares.

Twilight Sparkle has lost her quill(s). And her marbles.
Equestria better get undercover.
Otherwise... they'll have to endure.... a quill-less Twilight Sparkle!

For two someone specials.
