The H on Rimmer's forehead is much bigger in the first alternate universe.
In the first Alternate Universe, Rimmer's conversation with Holly where Rimmer keeps mentioning names and Holly keeps telling him "Not Dead" is take-off on the very first episode of Red Dwarf, where Lister keeps running through the crew's names and Holly keeps telling him "Dead, Dave".
The original title of this episode was 'Starknot'
The large 'H' on Rimmer's forehead in the first alternate universe pokes fun at the much smaller 'H' Rimmer now wears, compared to its size in the first and earlier seasons.
Historically it is possible for Rimmer to find a universe where he isn't a loser, Ace Rimmer was proof of that.
