Since we’ve got plenty of dark and depressing takes already, why not lighten the mood a bit with a joke take? Here’s what might happen to Ruby Roger.
When the Atlanteans invade Frostmill, Roger books it out of there as fast as he can (with Clark Silvers, of course). He drifts for a while before ending up in Palo Town, helping to evacuate civilians on his boat. He unfortunately ends up infected while fending off an Atlantean, but before he mutates, he throws himself into the ocean as Silvers and the people he was able to save sail towards the Stepstones.
Deep under the waves, Roger starts to grow larger and larger as he mutates, eventually becoming big enough to rival a White Eyes in size. He becomes more sharklike in nature, his lower half mutating into an enormous tail. However, he still retains his human mind and jovial attitude, eventually taking it upon himself to save more people and carry them to safe zones.
Though, given his status as an enormous sea monster, anyone who sees him likely ends up even more panicked than usual. A typical interaction might play out something like this:
Atlantean brig chases refugee ship, gets sunk before it can ram it. Roger appears and introduces himself to survivors.
Roger: “AHOY, LANDLUBBERS!”
Refugees: PANICKED SCREAMING
