They just waited, the soldiers left and you quickly started to pack up the things, to leave with the other soldiers when Price pressed a gjn in your back

Price "Where you think you going sweetheart?" He says. Gaz, Ghost and Soap just look at you, their guns pointed at you

Soap just smiles "Yer coming with us"
