If Series 3 follows the Thomas Hardy narrative...
will Alec Hardy and Ellie Miller get together?
I didn't believe this popular theory until recently when I read Chris Chibnall is a big Thomas Hardy fan and heavily influenced by his works.
Most of Thomas Hardy's protagonists have had unhappy romances/marriages and the rare happy union is where both parties have been previously married/in a relationship and started off being polar opposites and became friends while still married and then got together.
Personally I would prefer this not happen as it is too cliched. However, the argument still stands.
Never confuse the impossible with the improbable
