The more often I watch this episode the more I really like it on all levels.
We had the delightful nutty antics of Vincent and Hodgins with their arm-wrestling - two big kids together- and then we turn to tragedy with the shooting and death of the young English squintern. The team were all obviously devastated and reacted in just the way you would expect given their characters - hats off to the writers and production team.
Brennan getting into bed with Booth was handled with real delicacy - he was so protective and comforting, it obviously led to much more. Hats off again to Boreanaz and Dechanel, two fine actors. Then we had Booth heroic, armed and dangerous but still refusing to kill.
The sequence to the song 'Keep the streets empty for me' was loaded with atmosphere. Just another example of why this series is so good.
