Um... pardon my ignorance, but are you talking about the Titan Judas Contract story where Wally got a pacemaker (and I quit buying Titans books) or is this something else? Kind of quit paying attention to comics other than the next Fast Forward figuring Wally wasn't going to be in anything.
Of course if this is something else and it ends just as badly or not worse than the pacemaker or HIC.... I'd like to know that as well so I can also avoid it like the ten circles of heck.
