Woods (II)

David naturally noticed how serious Mark was and nodded. Even if he was concerned for him, he knew there was nothing that could change Mark's mind once he decided. Mark looked at Suzie one last time before he got down. Closing the door, he held the katana and crossed the street. 

He went into the woods, disappearing from David's eyesight. Mark looked around as he slowly walked. He went forward step by step, cautious. He didn't want a sudden attack on him. He noticed a few of the leaves and the trunk of some trees had purple dots on them. 

He went near the nearest tree and slowly observed it. He didn't want to risk anything by touching it. Observing it, he slowly murmured, "These are normal pine trees. But why does this trunk have purple dots like this? Is this perhaps a mutation? The trees are finally mutating and adapting to the virus."
