For Who Can? ASAM 's scene at Concord Hardward to play correctly, Old Paul and Hubert have to be present. If you only have Hubert there, the scene has not started up correctly. If you can, return to a save before Who Can? ASAM started, and try again. If not, and you are familiar with console commands, you can reference the quest guide
Who Can? ASAM for quest id and quest stages. Remember to make a save before using console commands, so that you can have a point to return to before you entered commands in case they do not work. Failing that, the next best thing is to use the Holotape to Quest Skip to the next Main SS2 Story Quest.
