The story follows author Julian (Miller), who was confronted in season 1 by grown man claiming to be his long-lost son, whose sudden appearance is a spanner in the works at an already difficult point in his career.
Over the course of the first chapter, we saw Austin (Theo) gradually form a relationship of sorts with his slippery father, with season 2 revisiting this unconventional family as they are faced with more life-changing quandaries.
Theo has been the most highly praised in Austin reviews, with the former Love on the Spectrum documentary participant wowing viewers with his hidden acting talent – but there are plenty more familiar faces in the Austin cast.
Here's your full guide to the key players as the comedy returns to our screens.
