Just happen to finish watching episode 5 of 2nd season thought to myself “I like her. She’s a good actress”. Then remembered she also has leading role on Luther (BBC currently on Netflix) figured what the hell been awhile since I’d watched Luther and haven’t seen latest season.
 anyway start season one episode one and to my shock heres Ruth’s character ‘Alice’, start talking about Dark Matter, black holes  the evil that lives there etc 

Mind blown
