Yeeaah, the video in which there's a body that looks like Starkiller. In a cloning facility
full of Starkiller clones and holodriods that can flawlessly mimic human appearance. Plus it's Sir Vader Liesalot telling us that it's Starkiller, which should in and of itself be enough to assume it's not.

That's true enough when trying to understand the natural world, but it doesn't make for good storytelling. Therefore, I go with the most improbable and convoluted option: Yes, he is a clone, but he's been a clone ever since he got stabbed in the back by Vader back in TFU1.
