I wish we could have had more of this in the show. Damien and Lenora are such great actors and I felt like they played off each other really well in this scene. Hal and Annie were so hilarious together in a way I just don't see Alex and Hal being but what do I know? I'll just have to wait and see in series 5.
@Khaeysa : yes, it requires one certain twisting-and-locking-into-place movement that can easily end into a miserable crumpled ball ^_^ (I've been doing origami all my life).Someone there knows their origami (or had the very good taste to purchase one by an origamist). But then, Hal would never settle for easier origami, would he?
