Martin is pretty much broke again and hasn't had a paying job in weeks (Why? F.e. because who wants to/can move when everything's covered in snow?!).

He unintentionally mentions it do Douglas (we all know how good Douglas is at probing once he gets a whiff of something) who offers him a loan Martin is too proud to accept.

So Douglas teams up with Arthur and Carolyn to boost business for Martin. This can be hiring him themselves (under false names, see Arthur's birthday present for Carolyn) or spreading the word to friends or coming up with an ad of some sort (make him a website or flyers...), whatever you like.

And of course Martin will find out about it and, after some initial embarrassment, be very grateful.
