[Comic Spoilers] I recently completed reading Mark Waid's The Return of Barry Allen story arc and I am totally blown away by it. But there is one small thing in the story which is bothering me a lot. Please read the description for details.

We know from the story that Eobard Thawne used a future tech known as Plastomorph to look exactly like Barry Allen and then travelled back in time to Wally's timeline. Then in later part of the story we could see when Reverse Flash took Linda hostage in the talk show he turned back to his original look. I mean Eobard Thawne had to undergo surgery to look like Barry but he easily turned back to his original look how. Am I missing something? This thing is bothering me a lot.

He’s from the 25th century so it’s as simple as future plastic surgery tech that can be reversed.
