Key points from Rose Reyonolds' interview

1. Described as a streetwise orphan with eyes everywhere.

2. 7x04 is a big episode for Tilly/Alice (in comparison to the premiere where see her briefly)

3. 7x07 displays Alice's/.Tilly's heart's desire: To be apart of something! Connections, family, etc.

Other points as well, but I do think Alice has the most mystery around her, so far.
