The pods are definitely not Black pearl. Maybe a cross. The leaves in the upper right of your photo look like they could be Black Pearl. I raise Black Pearl purely as ornamentals.

Here's a pic of the plant in the upper right:

Seeds came from the same packet. The fruit on this one look correct, that is round and black although you can't see then due to the angle of the shot.

Your first pic remindes me of my BP x Ghost and in the same year I did a white bullet habanero x Ghost. I can't recall if I donated seeds or not in the seed swap you participated in. But both plants look great.

I have one that looks like that from the swap. I never pulled it out of its 1 gallon container to make it grow bigger, but it grows well in there so its fine for now.

2nd year of pods. Overwintered well. Hot and a very small fruit taste but not bitter. I just use it as a mix with others for heat.
