However, arguably the biggest test arguably came in the final scenes of season three when Wendy sacrificed her own brother Ben (Tom Pelphrey) for the benefits of the cartel and safety of her family.
Wendy was visibly distraught by the decision but the fact she took it was one that proved her loyalty to Omar Navarro (Felix Solis) and place within the cartel’s hierachy.
But this kind of drastic action is one that seems worlds away from the Wendy of season one, proving the incredible transformation to have taken place within Linney’s character.
And should she continue on this path in season four, will she need Marty? Bateman weighed in recently during a virtual panel.
