That’s fair. But we do not know the specifics of that parallel universe Boimler’s face fur:

• How long has it been growing?
• Did he fall into the raisin fertiliser as a teen, prompting an uncanny beard growth?
• Might he even be part Tribble (on his mother’s side)?
• Or is it simply a Captain’s Chair-worthy toupee? I’m betting on the toupee, and so is Shatner.
