(I can only make out the basics about what is supposed to be going on with HEADSPACE, so my apologies if this in no way lines up with what is actually going on.)
Panel 1: Still inside the mental image of MAX’s head, in the padded room where MAX sits on the floor in a straight jacket. MAX’s father - rather, a mental image of his father - falls down face forwards, dead from the hole in his chest. Behind him stands GEORGE WASHINGTON, dressed up like a modern-day RAMBO.
WASHINGTON: It’s time to go, son.
Panel 2: MAX, still looks in shock at where his dad lies dead on the ground.
MAX: You just killed my father!
Panel 3: WASHINGTON steps forwards over the body of MAX’s father. He grabs for a combat knife at his side.
WASHINGTON (1): No, that would require he were real.
WASHINGTON (2): But none of this is. If it were, I would not be here, for I have been dead for over 200 years.
Panel 4: WASHINGTON stands over MAX, who looks up at him. He holds a combat knife by the blade, pointing the handle at MAX as if to offer it to him.
Ideally, the panel would be looking up at WASHINGTON alongside MAX to give WASHINGTON a greater presence.
WASHINGTON (1): Your so-called father was their latest attempt to control you.
WASHINGTON (2): I have come to help set you free.
WASHINGTON (3): You could stay here and let them win.
WASHINGTON (4): Or you can come with me, and maybe I can help you beat them back.
Panel 5: MAX, on the floor, looks at the knife that WASHINGTON is offering him.
Panel 6: MAX looks back up at WASHINGTON.
MAX: Cut me free.
