I need more Scamander sweetness now I've read that lovely "Newt comforts PTSD!Theseus". So... Theseus showing up in time to rescue Newt from GrindelGraves' strafing spells? Newt's homecoming after his trip from the US? New Year's revels at the Scamander home? Theseus teaching Newt how to ride a hippogriff? Prank playing? Writing each other during the war years?

Anything, just brotherly tenderness (gen, pre-slash or Scamancest, I'm okay with all those!)
