Mark yells for Alec and Lana to wake up; like soldiers, they both spring up.
The Toad starts blaming them all for leaving him, then he whimpers in pain.
Mark convinces the Toad to sit down and tell them what happened. It seems like the Toad gains a tad bit of sanity for the time being.
The Toad then reveals his tragic story: he tells them how he cared for Misty, hugging her and kissing her like a baby. Then he says "we" put her out of her misery.
"We" meaning him and the things in his head.
All right, so yeah. He's bonkers.
Alec takes him by the shirt and drags him into the woods, the Toad screaming the whole time.
Then his screaming stops.
Hmm, an ex-soldier and a crazy dying kid go into the woods. Wonder what happened…
When Alec comes back, he dryly says he did what he had to, and then goes to wash his hands.
