So we know that Bridgerton took a lot of inspiration from Pride and Prejudices for season 2 and I feel like their taking a lot of inspiration from Jane Austen's Emma for season 3. Both Penelope featherington and Emma Woodhouse are considered to be bironic heroines and there romantic partners both have a hero complex. Both couple's start out as friends and grow into lover's after a journey of growth and understanding each other on a deeper level. Basically I believe that Colin will be the Mr Knightley to Penelope's Emma.
