Definitely white. And my tree decorations have a colour scheme. I'm kind of OCD like that.
I feel compassion for him, as I do for all people who have contracted HIV - no matter how it occurred. The new antivirals available should keep him manageably healthy. I actually would have thought that someone living his kind of high-risk lifestyle would have been tested regularly and not end up with a diagnosis out of nowhere after a bout of bad migraines. Hopefully it's a wake up call for others to stay on top of their own sexual health. Sadly, it can happen to anyone - there are high risk situations and low risk situations - but really, all it takes is one bad decision. Very sad, and hopefully he uses this as an opportunity to turn his life around.
Btw... is anyone worried about Rick?
That last scene was awful for him and he looked so defeated. Also - it appears he got cut and walker blood is in his wounds. Apparently this means something in the comics but I haven't read them.
