When she puts on the necklace that belonged to Aleah, it's like she's representing her, so she stands on the other side of the cliff, symbolizing her departure, the scream is to show all the sadness they're feeling for her departure!
You can allmost feel the spirit of Aleah haunting there. Soothing yet such powerfull Doom Metal and what about the combination of singers? We got "Ares - the god of war" (Tomi) and "Siren" (Heike). Oh boy they sound so good together. Juha really honours the memory of his lovedone by putting all this together!
This necklace that Heike wears in the clip belonged to Aleah Stanbridge, she wore the necklace in the "Sinking Ships" clip. It was given to (Heike) as a gift after Aleah's death. If I'm not mistaken, Aleah should have recorded this clip... Without her, so they called Heike.
