Hyperaware of the time of day, Richie looked forward to the setting of the sun because then he could leave the confines of some building or another, he didn't have to move so cautiously. The one thing he fucking hated the most was how trapped he felt, like he was imprisoned but not unlike most prison sentences, death was the only way he was getting out of this one. Having died once already, Richie wasn't interested in trying it again, especially because the second time? It would stick. Turning into this saved his life in one way and twisted the knife in another.
The physical limitations aside, it seemed like most of the life he had before died with his humanity. Santanico worked her fucking magic and he and Seth were separated, left to go separate ways and there was nothing Richie could have done to stop him. And was he jealous of the preacher's daughter? Yes, in an entirely selfish way. Richie thought it should have been him to leave with his brother, the two of them back together like it always should have been, but a woman (or in this case, two, if you could count Kate as one) got in the way again. As much as Richie sort of despised Santanico at times, he couldn't help but respect her. She knew how to plan and how to make sure she got what she wanted. Part of his realized now that there was no way in Hell he was ever going to leave that bar with his humanity or his brother.
Introspection was put on the backburner for now because the sun had finally gone down and Richie needed to get out. Richie had ignored the nagging sensation that had been plaguing him since he had first showed up here, but nagging didn't really describe it anymore. What it was now was the kind of pain he had only really felt a few times in his life, those horrible hunger pains from the times in his youth when there wasn't a roof over his head anymore and not even an abusive parent to at least make sure he didn't starve to death. Richie hated that feeling, hated everyone that led to him feeling that way, including himself. And feeling that way now? He hated it all the more.
At the same time, Richie hated that he had to survive this way, thought it was disgusting, but there was no changing it now. Richie made this choice while bleeding out on the floor of some stupid bar in Mexico and he really hadn't had all his wits about him. If he hadn't been slipping out of existence, Richie liked to think he would have told Santanico where to shove her offer but ifs and maybes were the types of things that put people in their graves. Right now, Richie was walking the streets, following behind a solitary person, attempting to calculate the best time to try to jump her. He probably should have been less obvious about the fact he was tailing her, but he wasn't entirely in his right mind either.
