1 Prof. Jones: Junior, why are you talking with these Nazi thugs?
2 Monty: Shhh, dad! I have a plan. I'll keep them occupied, then on a count of three, we run.
3 Minnesota Jones: Are all his plans this well-considered?
4 Prof. Jones: It's an improvement. When we found the Grail he let the Nazis shoot me.

Professor Jones is of course talking about what happened in #101.

2013-05-23 Rerun commentary: I like the fact that they're just bickering amongst themselves while the Nazis are standing just across the river with guns aimed at them. Comedy gold right there, folks.

I also like the depth of field in panel 2, where Monty (the one who is talking) is in focus, while Sallah behind him and Professor Jones in front are blurred. They use this in movies a lot to draw your eye to the most important objects in the scene.
