My experience was slightly different. I've wintered Cubanella and Jalapeno plants in the dimly lit basement (trimmed to Y-shape). While Cubanella died (I likely didn't water enough), Jalapeno sprouted in spring and produced a fantastic harvest. 3x what I got in the first year.
This year I was planning to throw away my green pepper but it started producing a second harvest so I decided to keep it.
Wintering at room temperature makes them super susceptible to aphids though (they're weak and have papery leaves).
