A stranger appears within Mount Justice claiming to be a time traveler and the grandson of the current Flash (Barry Allen). The boy, Bart Allen/Impulse, soon gatecrashes the Garricks' wedding anniversary party and reveals his identity. The party is interrupted when they all learn that a villain called Neutron is on a rampage, and the Flash, Kid Flash, and Impulse head off to stop him. The Flashes defeat Neutron, and Impulse secretly administers a cure to Neutron's uncontrollable power. Through a nonlinear narrative, it is discovered that before Impulse embarks on his voyage to the present day, he bids farewell to Neutron, fully aware that the time travel is going to be a one-way trip. After he departs (and the events of the episode take place), Neutron reverts to normal, but is horrified to discover that the post-apocalyptic future around him remains unchanged. Meanwhile, Red Arrow and Cheshire travel to a League of Shadows base in Tibet where they finally find the original Roy Harper.

I'm back to talk about the crazy that was Bloodline!
18 September 2013 | by Artemis_CrockSee all my reviews

K, IDK where to start…K. I'll start with the fact the little Mrs. Jade deemed it appropriate to bring a 6ish month old baby with her to Tibet…You know what, FINE! Lets pretend no one knows she had Roys (what R we calling him now?) baby! No one knew, and it's been like a year now and she kept that crap hidden. Good for her! Her sister has no idea, and I guess she hid out in a cave. WHY NOT!

But I am not gonna watch this show and believe that the new (old?) evil kept the Real Harper in a cold room surrounded by about a hundred guards, that NOT ONLY let these young adults slip past them, but were ALL taken down by them? And they have no injuries from said event? But somehow The Real Harper has no arm!?!!! What kind of Hell did he have to go thought to end up with no freaking arm people?!

Also that baby who's old enough to have teeth, and begin talking can now identify her 'dad', understand Roy IS INDEED her father, AND realize there are two in front of her in order to say 'dadddys'? NOO! I draw my foot at THAT! Yes, I'll believe somehow this child didn't break its neck from all the fighting while her mother held her, But NOT THIS! NOOO!

….K, guys, on to the 'A' plot line.

So IN LOVE w Impulse! You guys don't even know! I LOVED him in Smallville! SOO BAD!!! I LOVE his voice! (@TheGuyFromTheWeekenders) I could tell I'd love him the flashback. And I was happy I spotted a dif. In his attitude, only to see a flashback showing that he's actually serious, AND funny….He's like Trunks from DragonBall Z…well Trunks was never funny, but you get the point.

Verrrry happy Flash didn't die, and Kid Flash is still w Artemis/KF. I wasn't ready 4 him to join the JL.

ALSO, I'm REALLY hoping this is the start of a bunch of time lines, and by the end of this season we will be 5 years in the past again/back to normal! Cuz we've jumped 40 years ahead, and it didn't fix the future, so I think they'll have to go back to 2011/when everything was normal.

…I just don't love the new team like I did the old. I'm holding out 4 something better….

Also, I love that KF & NighwIng still have such a bromance!
