I remember noticing Kirks sideburns at one point. Spock's looked lovely.
I went and googled Pike's because I couldn't conjure up an image of him with mutton chops. Haha I think he looked nicely greyed! Considering he's older than the others, he doesn't need to be so clean shaven.
Pike - I wouldn't kick him out of bed either
With or without the sideburns
