Welcome.
Here's my opinion. Butterfly bandages are not anything special really. Just above a bandaid. Here's my issue with it. BFB's don't stick well to hair. So, they would have had to shave his head to get them to stay. Could he have gone to the ER for this? Sure. But, they would use a medical glue if anything. Much easier to use, and much more reliable.
Agreed. I think it's an exaggeration of what was on his head, but I have no evidence to support this.
Sure. I think he's making a show of it.
It's hard to tell how serious they are. The one on the left side of his head, doesn't seem very serious at all. It isn't bleeding very profusely, and it doesn't appear to have any separation or swelling. However, the one on the right, does show some separation and some swelling. How deep it was is unknown. Neither appear to be bleeding all that bad. I am going to assume that there was never a bandage on the wound up to this point. If that's true, there is barely any blood at all, and not bleeding all that bad at all.
So, there's my opinion.
Oh, and you wanna see a head lac?

So, where's all Zimmerman's blood? I don't see any on his neck, nor any on his shirt collar area.
Odd that is.
