It is the Most Adorable lunch date ever! Erich puzzling out how to interact with Biggles and hitting on 'just like when he was hunting me, only in a more friendly way' is a thing of beauty and a joy forever.

I am also very fond of Biggles's later reactions.

Biggles: do you have any clue what these villains are after?
Erich: no idea. I'm sure this isn't connected, but I read in the news a few weeks ago that a distant acquaintance back home was in trouble and I'm slightly worried about his family, but there's nothing I can do about it
Biggles: I'll get on the next flight out
Everyone else: wtf, this is in no way your job, we have real work to do, what's got into you?
Biggles: Erich is worried about them, so I have to drop everything else now
