Minor character -- 2 lines

Alexandria is an alchemist that's gone crazy due to her being taken over by an alternate personality. She only has 2 lines in the script, but they are both spoken as if she were losing her mind quietly and unable to focus on something. 

We run into Alexandria as she is dazed and confused in her laboratory at Addermire Institute. Emily is supposed to neutralize her, but because of the 'No Touching' challenge, I do something a little more elaborate. Her death is quick and sudden as a result, and that's why she only has those 2 lines.

I did put English (British), but for this character specifically, I'd like you to take inspiration from Maggie Smith. Don't do an impersonation if you can help it, as I'm not specifically looking for one, but I won't overlook them, either.
