Anderson ... looks too young
I honestly don't care about this, but a significant proportion of the readership obviously do, so it's not going to go away.
Now Dredd's had a dip in the same fountain as Orlando, Mia, Alan and Emma, they might as well magic Anderson all young again, too.
Mike Carroll's techno-nonsense described Dredd's
dip as
full cellular regeneration, which, as late as Al Ewing's
A Home For Aldous Mayou (i), was being described as a completely new, innovative technology.
So, that one line from an older Anderson story (ii) about then-existing
anti-ageing pills interfering with psi-abilities no longer holds.
Can't see that happening, though, for ideological reasons.
