Well this is a chaotic episode. An episode idea that turned out to trickier than it seemed when we thought of it. The intended guest stranded in the countryside. Then a last minute run in from a mystery guest. I think it all works out in the end. The obligatory game has a pretty solid concept behind it for sure.
Needless to say, given the topic, SPOILERS abound.
And Full Metal Panic Fumoffu episode 2 is the Weekly Retro Recap.
