Alf's got a bee in his bonnet when his son Duncan's ex-wife Caroline rolls back into Summer Bay! What's her game??

There’s a surprise arrival in Home and Away this week when Duncan’s ex-wife Caroline shows up in the Bay with their five-year-old son, Bryce. A bit of warning would have been nice!

Why the sudden appearance? Alf for one isn’t buying her story that she wants to see how Duncan is doing following his horrific plane crash.

Is there more to Caroline’s arrival than she’s letting on?
