To all the people that keeps saying that it's a stupid move, remember that they're all strangers trapped in the Other side.Yes, The military acted stupidly by being vague, if you read it properly you'd know that the train coming and the fight with monsters was enevitable, only that the time wasn't fixed and the phone call lead to that happening earlier. The military can't lose the only lead they have on getting out by losing *the girls* -snickers- and the duo can't really trust strangers, recall the last guy they met, he was also a bit of a lunatic. The phone call was a risky move but it was a good one. I won't delve into it more lest I spoil the story.
