Zoe is in the process of taking a sample of PJ's blood for the test.
Zoe : It's really only a feeble little virus.
PJ : Well I'm just a feeble little man
After PJ has spoken to Janet Shaw and Maggie is still confused as to what's going on between Janet and PJ. Maggie offers PJ a cup of coffee which he refuses. She then gives it to Nick who is looming over her shoulder, watching her every move.
Nick : Hand me downs. Cheers.
In the CI office, after PJ rejects Maggie's help with whatever PJ is about to do, Nick comes in.
Nick : Well, if CI's done you could always come back and play with us uniforms. We've got a very special place in our hearts...
I definitely think that Nick knows about the PJ/Maggs relationship.
That's all from me for the moment.
