Explained why Joker was in the Mass Relay during the explosion. Hakket ordered him to head to a certain area. Mass Relays no longer destroyed, badly damaged. There is also a fourth option at the Catalyst.
Spidey shows up again in the season 2 finale, as do all of the heroes.
Compared to the last few episodes of season 1, the Loki story conclusion, I'm pretty disappointed with how season 2 ended. The New Avengers episode was pretty awesome, but after that it seemed pretty meh in terms of the story itself, and the final episode seemed extremely rushed. It should have really been made into at least 2 episodes to equal the season 1 finale, but we at least get to see every single hero introduced in the series in the same ep, reminded me of the Apocalypse finale to X-Men Evolution too.
I was going to watch the Mass Effect DLC but it won't load at my save place, damnit, so I have to restart the Citadel mission. And I got distracted by Ren, Rekon, and DoNothing to play MP instead. I will return to you, ME3.
In other news I am on season 2 of Avatar and I like it a lot more now!
