And why did the female electrician (in purple) need to jump of with the angel?

I suspect because she didn't want to live anyway, with her husband dead.

Those two weren't bad characters but they were so poorly served by the food jokes and Foon being so stupid as to spend that much on phone calls (so the planet Sto is just like Earth then, phones and all?) to win a competition. I liked Banakafalata and the midshipman a lot, but the whole gunshot wound thing undermined Alonzo's scenes. They should have made it a slight wound in the arm or something and then him hit his head going down; he'd recover OK from that. The writing was just sloppy.

The SFX though? Awesome.
