"I broke the speed force?".
"Yes Barry, you broke the speed force. It's going crazy, sucking speedsters into different points in time because it's unstable. When I tried to go back to my time period, I ended up in the 64th century. The 64th century for god's sake Barry!" Thawne shouted. Barry thought of what happened recently and replied "I was taken back about 1000 years ago. Why is that happening?"
Thawne was running out of patience but calmed down and said "You saved your mother Barry. All of this wasn't supposed to happen. Think of the speed force is like a dam. Now all the changes in the timeline are building up and starting to overflow and soon it's going to break." All this information took Barry by surprise."What happens if it breaks?" Thawne didn't even want to think about that possibility."Even I don't know but you can bet the universe that it's not going to be pretty. You know what you have to do Flash." Thawne said with a smug look on his face."No! No no no no no no! I'm not gonna let you kill her again. Not now, not ever!" The Reverse Flash was confident that Barry was going to break."You know, Barry, the you from the future, the Barry that I know, he's not this stupid. If you don't take me back to that night, you will end both of us!" Suddenly, Barry realized that he built the cage he was in so he phased out of it. Thawne's reaction was not expected."Do whatever you want Barry, just know this. The Flash of this timeline, the one with the yellow suit, he is your future wife's brother." Thawne said as he tapped his palm and showed him the footage of Wally from earlier that day. The video showed Wally being impaled by the masked speedster known as The Rival as Barry whispered Wally's name shocked by the revelation."He's not healing fast and soon, your future brother-in-law will die because you are being selfish. Knowing you, you will not be able to live with yourself knowing you are responsible for her brother's death. Will you be able to look her in the eye and say that her brother is dead because of you" Thawne said knowing he won."Enough. Why can't you do it?" Barry said in defeat. "You have a better connection to the speed force. Only you can take me back to that night. Lead the way Flash." Thawne said getting ready to time travel with Barry. Barry got up realizing that no matter what happened, he could never be with his mother.
When they got to the past, Barry went to place where Star Labs was in the future while the deed was done. The Reverse Flash came and told him it was okay to go back."It's best to go back to the time you left. Things are finally back to normal. Well, for me at least. For you, I guess you'll just have to wait and find out. See you soon Flash" Before Barry asked him what that was all about, Thawne already ran to the future. By the time Barry got back, he was exhausted both physically and emotionally so he went straight to sleep without talking to anyone.
When Barry woke up the next morning, he didn't find Iris at the house and the answer he got why she wasn't there wasn't the one he expected. It turned out that some things had changed and he wasn't going to like them. Iris wasn't there because when Joe had told her that her mom was still alive, she didn't take it too well and their relationship took a huge blow. They weren't even on speaking terms.
When he got to Star Labs, that's when things got complicated. The kid he saw when the speed force was going haywire was there, and he said he was the grandson of Barry Allen, the grandson of The Flash.
