My theory is that Nergal is in Love with Leon and jealous of Cliff like, the time when Leon Mistake him as Cliff and grabbed him in the room Leon said something with a Blur and Negal's face went Dark and it happened again as Leon wake up from a Nightmare as he grabbed Nergal as he woke up and Negal seems to know who Leon was thinking about and seems to be annoyed by it but yet again, it seems like Nergal is in Love with Leon but Leon will never love him back as we all know that Leon only has Cliff in his Heart and Nergal Realise that and is just Jealous of Cliff because his Love will never look at him the same way he look at Cliff and that explains why Nergal is always taking care of Leon and always thinking about him while he was away, as he is now Angry that Leon was wearing the Earrings that Cliff gave him
