This may imply several things. It is possible that the victims were at least somewhat prepared to receive a command, so being given one did not cause automatic refusal / resistance. This preparation to receive a command could be from several circumstances:
- Geo Cache, Pokémon hunt: Phone is confused about the elevation. BG, a trawling potential murderer, tells them it is under the trestle, down the hill. They hesitate, but obey as the command makes sense given the game. BG then follows them down.
- A meeting for some purpose: The victims are prepared to meet some one, or be shown something, or be given something. Though not expecting BG per se, he and his commands are not so unexpected that they refuse to obey. BG then follows them down, or there is a person (s) waiting for them.
Though I think a meeting for any purpose would have been referred to on social media by teen age girls, the lack of such references cannot be used to rule out a possible meeting. Some criminals may well have gotten very social media shy and prefer verbal arrangements and cautioned the victims not to "go social media".
Though a certain number of teenager would instantly disobey a "no social media", caution, the victims might have followed it for a variety of reasons. This is especially true if only one victim was fully informed about the meeting. As to what the meeting was for, there are a lot of possibilities... .
