Eastmouth: Season 2 (Small Town Mystery/Adventure/Horror)
Liz Moss for Yellow Eyes-2
The second of two shape-shifting aliens that have found their way to Eastmouth through a very long chain of events. She's been held underground in captivity for at least a century and has no greater wish than to return to her other half. When in human form, she has a very calm and almost radiant personality. When she transforms into her natural form, she can no longer speak through vocal chords and resembles something closer to an alien spider than anything else.
She'll be found in the latter half of the season and help out until she's reunited with her spouse.
[Upon first being found in the subterranean laboratory. She senses that one of the humans can understand her and transforms before their very eyes. (calm and almost hypnotic)] "I see that you can understand me even in my other forms." [Obediah explains to her how he can understand and asks her why she's caged down there.] "Those Fae are not kind to us. I remember little before I was sealed here. Another presence, maybe. One that felt close to me."
I quite like the take. You give her a voice a slightly otherworldly quality.
