Clara & Mia: Stitched, Or Together From The Start?

Okay, so ever since I started writing my Fran Bow Fanfic, *check it out*, I've had Fran Bow on my mind a lot. And like anyone who's basically ever played/watched someone play Fran Bow, there are a lot of questions.

Was it real, or a hallucination?
Did Fran REALLY kill her parents?
Is Fran dead?
Is Itward a metaphor, or a real being?
How did Clara and Mia *really* die?

STAY TUNED! DUN DUN DUN!
