Well I'm sure she was right there for visitations or long phone calls where she gave his fellow comrades nicknames and asked about them, basically offered as much support and friendship as he would let her. Which is exactly why she will support his love of magic and always pretend to be amazed by his tricks. Offers to let him saw her in half, etc. I'm thinking maybe she made it known ucla was her dream school? She was dead set on going there so it could have helped him decide that was where he needed to be too?
