From Episode Summary:
Bob is back. His brain surgery caused an infection which leaves him in a bad shape when found. He is put into a medically-induced coma. The team travels to Mexico where an antibiotic-resistant strain of TB is killing the Zapatista Revolutionaries.
Nice to see Rachel and Mayko team up. I'm in love with Mako by the way, leg or no leg. I hope Carlos is okay, can't wait to find out what happened to him there.
I don't understand why Oliver Roth is still walking around. Shouldn't that guy be in jail for kidnapping or practicing surgery unlawfully or something? Poor Bob, wake up soon and nail that guy.
Anyway a nice return. I'm still hoping for some fum last season cameos. Who knows.
