There is definitely going to be a back story with Niamh, isn't there?
-she isn't really Irish.
-she accidentally murdered a GP, by strangling her with her scarf, and decided to take over her identity.
-she is really a children's entertainer, and part time window cleaner.
all of this will come to light at the wedding of Niamh and Al, leaving Al heartbroken at the altar, but willing to stick with her no matter what.
