I just mean at this point in the future, in most timelines, Logan has some gray creeping in. Just thinking that would make sense at this point. Especially in the movies, if they're going to pull him from the FOX-verse pre-Logan, as Jackman hinted was the case (though he may not fully understand multiverse, to be fair, and he could be playing a variant from a totally different universe). In both timelines in DoFP, the dystopian one and the hopeful one, it was 2023 and he had the gray around the temples. It's a good look IMO.
