“I’m excited to spend time with my little family until a possible season two,” she said.

Lydia also discussed her friendships with her co-stars and how important it is for them to discuss how much they have been paid for acting gigs.

She said: “My colleagues and I have a relationship now where we talk about job compensation… It’s so hard to have those discussions and say, ‘Oh, what are you getting paid for this? Does this sound about right?’

‘But you talk about everything with your best friends, so why is the topic of finances or how much you earn something we don’t do?

‘That was a great lesson for me. And then sharing industry advice and supporting each other when we go through tough times at work.”
