What about Brenda?

This is bugging me. During Night Shift they brought a woman in to the hospital by ambulance. If you recall, this ambulance caught fire and Jason had to rescue this woman from inside. The woman ended up having plastic surgery. The name on her door said Barrett. Toward the end of the show we saw her watch carefully her best friend Robin Scorpio and her ex Jason from a far. If that wasn't Brenda why was some weird woman watching them? Let's just assume that was Brenda.

Now, let's examine Coop. It was revealed everywhere but on the show that Coop Barrett was, in fact, Julia Barrett & A J Quartermaines son. Why did this fact never come out? We just have a boy running around with the same name Barrett, working under Sonny (by blackmail) and no one thinks to ask if there is a connection? You know because of the last name Barrett?

We have a woman who appears out of nowhere on Night Shift and a young man named Barrett running around town, both storylines end without connection to the Barrett family. What happened?

I want resolution General Hospital!
