Portia should show Ric a modicum of gratitude for not focusing on who altered the lab results. That is exactly where he was headed. As Ava said, it took her all of 3 seconds to figure it out.

The other good thing Ric did was not encourage or even mention to Heather that she has grounds for a lawsuit against GH. Portia was acting out of fear for her daughter--but her actions put the hospital at risk.
