"Love, Sri Lankan Style" is all about Steve and Mimi's relationship. Drew finds that Steve is finally back in the area and is able to track him down. Drew convinces Steve that it's time for him to get back with Mimi, who has been going out with Larry. Steve agrees, but he also has to convince Mimi to meet with Steve. This takes a little time to get her to agree to do so.
The subplot of this episode was Lewis and Oswald's new business attempt. They decided to try to sell a Rubbermaid knock-off. I think they called it "Tuppermaid" or something like that. Nora, from Drew's old job doesn't like that they're doing this. With them selling those products, they're cutting into her sales, so she makes sure that they're next order doesn't get filled. Nora convinces Lewis and Oswald to work for her and they'll all make money.
When Steve was in Sri Lanka, he apparently met a woman, Padma and had sex with her. She came to Cleveland for him. She's in love with him and wants him back. This is obviously putting a big crimp on things for Drew, since he's trying to get Steve and Mimi back together to get Mimi out of Drew's house. When Steve confesses to the additional affair, Mimi pours hot tea all over Steve's crotch. At the end of the episode, Mimi decides to go back to Larry.
This was an average episode overally. The acting seems to lacking in quality. I've noticed this more and more in the last season; it's too bad.
