Null is trying to social engineer Elaine into hooking up with Ralph so that they can be miserable together, but Elaine is not stupid. She sees Ralph as an old fat pitiful alcoholic on the internet and she wants to make him better. Then there's the parasocial fantasy of kicking the habit together with your favourite Youtuber. She probably grew up around alcoholics and wanted to save them, so she's projecting that fantasy on Ralph. She should be projecting that fantasy onto herself.
In reality, why would Elaine put up with Ethan Ralph in Mexico, when she can clean herself up in London, make herself semi-presentable and then go bag some Russian oligarch with a yacht? Lots of those in London. That would be a real p0wn, not Ralph.
