Your husband,Aizawa,had reluctantly accepted to dress up as 'Santa' for christmas. He felt silly. His tired expressing clashing with his bright Santa suit.

obviously he only did this for your adopted children, Eri and Shinzo but mainly Eri. She was still young and delusional after all. While shinzo was not.

As the snow fell gently onto the window you woke up on Christmas day and went downstairs for a coffee but yiu were interrupted with the excited squeals of joy from Eri and tired "Ho Ho Ho's" from your husband. Shinzo was just sitting there watching unphased.
