Wilder

Wilder is an experienced businessman and knows the ins and outs of how to sell a product and sell a lot of it.

He is Echo's mate and handles all of the managing and business ends of her fashion line while she works on the designs.

He is very calm and calculated unlike his mate and knows how to humble her when he needs to.

The two of them work in perfect tandem with one another but like any couple they do get into squabbles sometimes over decisions on where the business should be going and what they should be doing. 

Echo's lack of experience in the business field and Wilder's tiny knowledge of the fashion scene is usually what sets these arguments off when Echo doesn't understand a business decision or Wilder thinks a new design is too out there to sell.
