Emily shouldn't have phoned her mum wtf! I get the impulse and desire but as ultimately this is just a game show if she can't bear to be away from her son she shouldn't have gone on. Man she's annoying. No stop bloody calling everyone! If you REALLY must leave messages for them with other people you're not directly connected to!!
The resources yes they wouldn't be employed for your average missing person - but if you're considered 'subversive' they would be and don't be under any illusion that only applies to terrorists. Just talk to ANYONE involved in campaigning against the govt. CND, animal rights activists, welfare rights activists, anyone with communist/anarchist sympathies...
They'll tell you they have experience of their phones being tapped, mail going missing, friends and family realising at a later point they told a stranger at the bus stop/library/supermarket something about you that could be compromising/misconstrued/make you vulnerable.
I agree rural is best option. Either with or without a network but with my personal life experiences I would go NC with everyone! Ultimately the only person I really trust is my daughter. Re rural v urban the other problem with urban is other people!! Lots of witnesses!
If it was real life and I needed to do this:
Destroy all electronic equipment, don't leave them for the hard drive to be recovered.
As I said total NC with everyone
Head somewhere rural where I have no connections/history. If real life different country. In fact several different countries. Some are easier to get into than others but people do get into even USA illegally so clearly it can be done.
Not use the money unless absolutely necessary. If rural bartering services for food especially at farms. Make use of wild fruits and veg.
You don't even need a tent. It's possible to make a shelter from branches etc or use a natural one like a cave.
Source freshwater.
Remove my birthmark (unfortunately I have one on my face so difficult to hide.
Disguise self as a man.
I haven't though about this much honest guv
I'm sure others will have ideas to contribute too.
"If you had all those resources looking for Emily and the other one, then they would have the helicopter up in case they did a runner over the fields." True
Think any of them will remember that northern Ireland is part of the UK and therefore fair game?
