Maria Connor Sutherland (Samia Smith)

[Perdita]

The inactivated credit card, though very convenient, is one of the more realistic aspects of the storyline. Caz was living at Maria's house and able intercept her post to get hold of the PIN. That's one of the reasons why it's advisable to have your mail redirected when moving house.

Very true but Maria did not move, only went to meet with her "husband" for a week or two ... but Caz very easily could have got hold of the letter with the pin if she was the one to check on the mail, even while Maria was still at home
