Good news: the seeds will probably be viable. Bad news: don't think the green fruits can continue to ripen off the tree.
Suggestion: if possible, better frost protection.
I'm glad. Today I cut one by the middle, it was green but rotting, I guess that was due to frost. The aroma is good! still being green ... seeds do not seem well-developed ... I hope that the yellow and wrinkled has any viable seed, but, the only hope is the one that is red has viable seeds..., still needs to mature on the plant.
Yes, the next frosts I will use the blanket again, I have to use anti-freeze blanket again, what happens is that previously had used and also had frozen leaves touching the blanket, but should have left it on, that was better than this.
