[X] Direct attack. Draw fire first. These people are going to get somebody killed, even if they are Gang members. You might want to do something. Use whatever intimidation tactic you can and brute strength to try and force them to disperse. It doesn't look like Emma and Shadow Stalker are going to do anything soon and you're still worried about them. You can probably survive getting shot and you regenerate. They don't.
[X] Just watch. I would not be told to leave and I would follow even if they tried to get rid of me. Talk and figure this out, but only interact if Emma or Shadow Stalker were in danger.
[X] I didn't come here just to have them intimidate me away, but I should try to be a bit nicer and more understanding. Maybe I could get through to Shadow Stalker, even if some parts of me weren't convinced. Maybe I could try to help?
