The fact is...

Get enough facts together and the facts become clearer. The subtractive quality of facts are not reliant on the quality of facts. However when stepping away from facts, opinions may begin to take their place. Are counterfactuals facts?

The evil twin!

You know a story is beyond good when it uses the "it wasn't me/him/her it was my/his/her evil twin" as a plot twist. Normally people go as far to pull this one out after an afternoon of drinking soon after they move onto the rums. But to pull out the evil twin is also a pro-Nazi flying spy is really hitting a new found peak usually found in the midst of the inevitable tequila or mescal shots.
Irresponsible? Perhaps. 

Duh! You think so?

It could be just that Nazis are not very good team players. Sure there are bullets coming in through the cabin. Sure someone has to drive the plane around the sky. Sure someone else has to travel around backwards all the time. But, can't these two realise they're on the same team - despite how sick and twisted the ideology that brought them together? And here's the problem, teamwork or a lack of it tends to be self serving. It doesn't necessarily allow team members to look beyond the task at hand. So it's great for getting things done but not necessarily good at differentiating between right and wrong. So possibly it might be a good thing to shoot at sky Nazis, so that they might begin to question themselves. That can only be a good idea. 

Ain't nothing like a good plan.

Like good music a good plan is a thing of beauty. Just as a good inky panel full of shadows and strangled light is a beautiful sight. No denying the urgency. No denying the intent as words and image combine faultlessly. At this moment everything is going to work as planned. Without giving too much away things do go wrong after this planning session. But... it's more dramatic that way.
