Samara was once a child gifted with the psychic ability known as nensha. As she was unable to control this ability, Samara would mentally affect those around her, including her adoptive mother Anna.

When Samara was kept in the attic, she said the noise the horses made bothered her, so she psychically attacked them, and made them all terrified of her to the point of running into the sea and killing themselves. The reason the horse on the ferry kills itself is that Samara left her imprint on Rachel.

On the other side of Glasgow are the Rangers F.C ultra group The Union Bears. The Union Bears are known for their elaborate fan displays and their support for Northern Irish and Scottish unionism within the UK.

The nickname Teddy Bears became popular during 1970s, inspired by Cockney rhyming slang. If one were to imitate a thick Glasgow accent, Bears will sound like Bers and that then rhymes with the word Gers - a shortened version of Rangers.
