So did ( Spoilers)

Just watched this and liked it alot , it had a bit of the High Tension type twist but it was really fun and brutal at times . The version I saw was dubbed and had no subtitles so in the dialogue I don't even know if it was mentioned or just truly meant to be open , but the kid with the glasses and the mulatto kid who escaped the tent massacre , did they actually survive after helping explode the truck and get left behind or was Sam and the Man going to go back and kill them?
