Barry Trains Jesse In Upcoming Episode Of "The Flash Season 3 After Becoming A Speedster

As a recap from the previous episode of "The Flash," it has been featured that Harry Wells and her daughter Jesse from Earth Two returns to their Earth and reveals that the Jesse has now acquired the powers of a speedster. It came as a surprise to everyone, but Barry was willing to help Jesse amidst the transformation and is willing to train her as well. The upcoming episode will feature the effect of that training.

It has been reported that Jesse won't be so fond of Barry's rules in becoming a speedster and might even be on rogue. This may result to her being in danger as she stirs away from Barry's offer to help her. Nevertheless, she will be of great help as Captain Cold returns to Central City in the next episode of "The Flash" and he is not alone. Along with him are the two new villains that team Flash will encounter, Mirror Master and Top. Together, she and Barry will save the city from these three villains.

Captain Cold Returns To Central City, But How Could He Be Possibly Alive?

Captain Cold's return will come as a surprise since his character has been killed off already in the previous season of "Legends of Tomorrow." However, since Barry has shifted the timeline countless of times during the first two episodes of "The Flash," this may have resulted to a change of events in relation to Captain Cold's death. Thus, this depicts another consequence to the action of Barry in continuously altering the timeline.

"The Flash" season three airs every Thursday on CW.
