1. While most things surrounding Game of Thrones are pretty uncertain, one thing's for sure – Maisie Williams (aka Arya Stark) and Sophie Turner (aka Sansa Stark) are the actual best of friends IRL.
2. From day one they've been inseparable.
3. And we are SO thankful for it.
4. They've even given themselves a joint name, they're so close.
Plus Mophie has an excellent ring to it.
