Plotholes

What are your favourite or little known plotholes you've noticed in dynasty?

Spoiler ahead!

So when Steven comes back in the finale and him and Fallon are talking at the piano, Liam rushes in to tell her the baby is coming and she says to Steven *'I will tell him about you later'.

Yet both of them knew each before Steven left, Liam even went to Steven's wedding and his grandfathers funeral...

Curious what other little (or big!) plotholes other people have noticed that aren't always obvious
