Thanks for this great guide! Amazing being able to finish this in less than 2 full turns... with an A-rank, no less. I used Ted instead of Freesia, though, because he has more health and his Show-Off Potential is really useful when you're running past all those Imperial fools.
I came only to see where the hell that bomb was. I was at the mark with the Edelweiss and the train was in the middle, but for the life of me I couldn't find the bomb. And it was the end of the turn, so I was afraid to experiment and let the train move in case I failed.
I might be wrong, but it seems that some potentials are random? With Alicia I got a first aid boost or something like that, i hoped i'd get double movement. :( It's really sad that ranking in this game is based on speed, not tactical decisions or clearing the whole map... makes it kinda dull this way. Thanks for the guide, though, it's great!
