Cool, so I expect Grayven's done all the proper science beforehand? Performed a study that confirms that the cutie marks produced by a previously thought to be extinct disease are the same as natural ones instead of basing it off of word of mouth related to a single incident? Tested the hypothesis that ponies with cutie marks are tastier prior to submitting it to what passes for Equestria's scientific community beforehand?
'Cause, ya know, not doing all that would make this whole thing bad science.
Well renegades not a scientist, so not doing scientific things is not that weird.
And Sunset, an expert in magic, seems to think his theory is pointless.
