The Watchtower was filled with Superhero's of all kind and even Founding members of league were also Present in the watchtower as their was currently no villain activity going on planet. Flash/Wally west was talking to his Friend Green Arrow in Cafeteria while drinking his soda and then he said " Today is really quite day . there is almost zero villain activity today and even Bat's here on watchtower ."
Green Arrow replies saying " I don't know man , whenever there is this kind of silence and free time in our life then there is definitely something big going to happen." he just finished saying it and then a screen appears in middle of cafeteria . same happened in many different places in Watchtower and there was timer of 30 minutes on the screen with a note written on bottom of screen saying *Livestreaming in 30 Minutes.*
"And I jinxed it ." Green arrow says this looking at screen . Flash reassure saying " Don't worry about it , I was already expecting some call for mission at least it's not Hostage situation or Big Villain attack ,just a screen on appearing in middle of Watchtower that say their will be a Livestream in 30 min and I hope it's Just some Big Prank by someone instead of some New villain Monologue speech ."
" All Justice league Founding members report in Main office . this is not a drill " it was Batman voice that could be heard . Flash said " Well there is my call , let's talk later ." "Sure " Green Arrow replied and Flash was out of there in a red blur .
In main office
