Although these are good points, this is L&P's reality. In his reality, are there cameras in or outside of the store? Was it self-defense during the jogging event? Dylan and Sophia could have walked away or jogged somewhere else; remember, Sophia said we could go elsewhere, but Dylan approached them and told them off. The point is that L&P's reality completely differs from everyone else's. IMO, L&P has to project Dylan to be somewhat of a protector or defender because that's his MO for this character. He did it in the park and club with Sophia. Plus, it gives him another reason to use Dylan's ninja training or MMA fighting instead of going to waste from a plot perspective, as it would have been pointless to introduce his training from the start.
I wouldn't be surprised if he does end up fighting the outlaw. As you can see, the alcohol was bagged to the left of the biker or "outlaw."
