This isn't much of an update but I have a lot of nervous energy right now and it gives me something to do.  Turns out the veins in her arm are too small and they couldn't get the picc line in.  So now they are doing a central line.  I'm not 100% sure of the difference and it seems they are nominal.  The outside of it will be on her chest rather than her arm and it will leave a small scar.  Small complication but it's delaying her getting to recovery.
