Wesker doesn't really 'do' Christmas, not even the secular British Christmas: in his mind, there's far too much commercialization concreted onto a religious festival ironically celebrating a God Who encouraged His followers to help the unfortunate and dispossessed.

But, he's not above offering gifts to his dear ones, in this case, a copy of "A Christmas Carol", following the example of The Tenth Doctor in Deerington.... only these copies will be delivered in the manner of Santa Claus..

Yes, you will have a tall figure in form-fitting black climbing down your chimney and leaving a package on the nearest table or desk...
