Wells (Tom Cavanagh) will cause problems for Barry (Grant Gustin) and his team in the upcoming episode of "The Flash."

In the episode titled "The Present," the synopsis (as per CarterMatt) reveals that Wally (Keiynan Lonsdale) is eager to help the red speedster in his fight against Savitar. The Kid Flash has been wanting to be part of the action ever since he discovered his powers. Unbeknownst to the others, he has been training under Wells.

When Barry learns about it, he will not make a secret of his disapproval. Wells is someone the whole Flash team cannot seem to trust completely. He came from Earth-2 supposedly to get Barry to train his daughter, but the others suspect he has other motives.

Barry does not know what Wells has been teaching Wally, hence his worries. Besides, he promised Joe (Jesse L. Martin) and Iris (Candice Patton) that he would take full responsibility of Wally since he was the one who triggered Flashpoint.

Barry has a lot on his mind lately. Aside from the double threat of Alchemy and Savitar, his relationship with Iris is not going as planned. Every day, it's as if they both have more important things to do than talk about their feelings for each other. For instance, Barry needs to go to Earth-3 to ask for some much-needed advice on how to defeat Savitar from Jay Garrick (guest star John Wesley Shipp).

Last episode, the red speedster was kept busy with an alien invasion in the city. He had to ask for the Green Arrow's (guest star Stephen Amell) help to fight the extraterrestrials determined to cause mayhem in Central City. The Dominators proved to be too difficult to contain that the two had to call on the Legends for help. Cisco (Carlos Valdes) also had a brilliant idea to ask for Supergirl's (Melissa Benoist) assistance.

"The Flash" season 3 airs Tuesdays at 8 p.m. EST on The CW.
