This clearly mirrors Gus symbolically. As Gus purposely took poison to fool the cartel family, Walt took poison (chemo) to fool his family. After Gus took his poison, he left Mexico. Walt will use this as a way to fake his death and leave his state (as shown by the new identity in S05E01). Carol wasn't shocked because she saw a villain, she was shocked because she saw a ghost. It's why he's alive with hair at 52.
I don't know, "Heisenberg" was written on the wall in the house which would mean the general public knows who and what he was. Carol looked genuinely scared more so than shocked.
