Wouldn't Zoom wonder why his remnant didn't return when literally nobody could've stopped it? He managed to stay away from Time Wraiths on his own for almost 3 years even if he figured out his remnant was killed by one, he'd still wonder how it was killed.

As for Savitar he existed in a timeline where Eobard's future was erased because of Eddie's death so it's impossible for Eobard to have learned of him in his past. Even if Wells/Eobard learned of Savitar through Gideon while stuck in the new past there's no way he didn't learn of Eddie's death. Unless his very arrival in the past somehow caused him to jump into the new timeline he would create and every future alteration unfolds at once, but season 3 pretty much confirmed that nothing is pre-determined so I don't see why Eobard would be the exception.
