I find that in this clip http://www.etonline.com/tv/180420_arrow_season_4_sneak_peek_thea_doubts_everything/, I am reminded of Aqua not only through her voice of course but her mannerisms and emotional integrity. As much as I loved her as Aqua already, I really think that if she does come back for 2.8/III she will be able to bring an even greater emotional range to her line delivery and performance since she has gotten more experience playing this kind of role of on Arrow.

Ugh...Willa might be one of the worst actresses I've ever seen.

There are many worse than her. She isn't even that bad.

Yeah, most of her lines in BBS were poorly delivered but she has improved as an actress a great deal.
