Casualty - can anyone help me?

[JonesTheSteam]

Only watched it from about half-way through tonight and haven't seen it much recently.

Did Nathan get stuck with an HIV positive needle?

What has happened to Ellen - the nurse who had a relationship with Harry and a molar pregnancy?

TIA

I haven't seen tonights but Nathan pricked himself last week while picking up a rubbish bag.

Ellen was in the last one before the break as she gave Nina & Abs a VW camper van she ended up having treatment for cancer. Maybe she had a couple of weeks off!

Thanks!! xx

(Love your name by the way!!!)
