My reading from that is that he owes Hector for shooting Hermano and has Hector living in fear for WHEN he is gonna kill him. "Is today the day?"
Whether Gus is doing this because Hermano was his lover/friend/business partner/cook doesn't really matter, the message is if you f**k with Gus he IS gonna make you pay and whenever it suits him.
There will be no forgiveness for Walt, he will HAVE to kill Gus or Gus WILL kill him
