Not a Datil

[Jusplayn]

I germinated 3 Datil plants last spring and planted them all in the same large container.
Two of them are putting out Datils like crazy.
One of them is putting these out, not Datils. They are hot(jalapeno-ish) and a little citrusy.  They have a huge seed ball that almost fills the inside of the pepper.
Someone have an idea?
Thanks in advance.

 No clue, it could be a cross... My out there guess is biquinho pepper, but those I thought had a more prominent point.

Billy Goat?

I don't think it's a goat pepper, at least doesn't look like the pics on google

Think maybe it could be the Jamaican Hot Cherry?

Ajijoe, have you checked out this pic?
I think I got these seeds from you.
