The episode was called Hush. I had a hard time sleeping after watching that episode, it left me deeply disturbed. I saw the special effect/behind the scenes for the episode and it took away the scares for those Gentleman and henchman figures. The last episode of that season (four), also kept me up at night. It was based on a battle between Buffy and the first slayer but not before her group being taken out one by one.
Why would you keep a desktop wallpaper of those Gentleman?
Thank you so much for your kind message. I'm trying to indulge in my hobbies and interests (including fragrances!) as much as possible. I'm happy I (re)found basenotes and decided to give being active on the forums another go!
