Assuming Silas' lover is not THE Petrova, and Silas/TVD writers still have plans of bringing her to life at some point which actress would be best suited to play her on TVD?
I'd personally go for an unknown and my choice would be Michelle Argyris
Your choice(s)?
I just went and Googled the actress you mentioned and she is beautiful...so definitely fitting to be on the show! I'm still leaning towards the Lover being a Petrova. I'm not sure who else would be good. I'd have to play around on the computer and search for a while. Maybe I'll get back to you later today or tomorrow with another face/girl for this role. :) I really like your choice, though.
