i wonder how doha managed to raise a flag. I don't think merely separating from bada wouldve done it because both of them were alone and the killer doesnt rly choose his victims so the killer couldve gone for bada (and I dont think Doha would want to risk that). Doha must have done something to ensure the killer would appear in front of him and not bada.
