For the sure reason of  getting people to clam the hell down on why some many of the new hero in young justice look older I find it hard to believe that there is a time skip mostly because of this.

Happy New Year!” is the first episode of the second season of Young Justice, and the 27th of the overall series. It is scheduled to air on April 28, 2012.[1]

The Team takes on the intergalactic bounty hunter Lobo… as a precursor to an alien invasion![1]

And in the frist season finally it was New years when they all kissed and stuff so how could there be a possiable time skip.

 Unless it the next new year we have to see till than 

But we only have 5 more day till than , well including the day it comes out 4 if you don’t lol
