The only reason i keep saying Thai or Thai subspec. is because, well, Thai peppers are whores - just throwing their pollen everywhere and giving you random offspring and who know's who the father is, haha. I am going with errant seed as with AJ. Just from last year to this year alone I have 3 Thai crosses that Were not intended or even known about. I have a black Thai that crossed with my black pearls, I have a Purple Thai that crossed with what i'm assuming was my ornamental house peppers, and then I have a cross of Thai Sun with bird's eye. These were all volunteers from last years seed that was dropped into the pots.
