I recognise the people in the third one but I can't place it, and then there's Elizabeth and Jack, Wesley and Gunn, Boromir and Aragorn, Ronon and Teyla (which is not so much with the tragic now as the tragic backstory), Babs and Black Canary (mind blanking!), and then Gert and Chase. All you need is Wash and Zoe and I'll be in pieces.
