I think with Orlando's skills he can at least make cute banter between Darcy & Pietro.
I am not sure for any relationship yet, but funny building banter or a friendship that does not end or come to quickly in a relationship would be welcomed to see.
But the cast has allot of operutunies to grow, Pietro and Darcy(BTW I Love that this was Darcy's 616 debut it seems, will just increase the value and history of the book!) are good characters to have as part of any books main cast and how they will work off each other I'm looking forward too.
