Summary
It was both Heaven and Hell wrapped in one. Richie had no concept of personal space. His shoulder and knee were pressed against Eddie’s while he talked a mile a minute about something Eddie wasn’t paying attention to. Not because he didn’t want to, but because he couldn’t. He couldn’t focus on anything that wasn’t Richie Tozier.

Summary
Taking a moment to think, Jane slowly looked at him. “You said… that Vecna was the reason you had powers. What if you did not lose those abilities and when you died they activated once again?”
It was sound logic. It would also explain a lot of what was happening around him. Will has noticed when his emotions have gotten the best of him since he's been back, that the lights would flicker or items in the room would shake.
