Prior to the release of The Umbrella Academy season 2, showrunner Steve Blackman promised there are a ton of Easter eggs hidden in the new episodes.

“There are tons,” he says. “We specifically wanted to sit down and say, ‘Here are the Easter eggs we want to put in, let’s make a list of them.’ They’re everywhere. I think the fans will get a real kick once you start realizing what we’ve put in.”

Now, just a week after the season's release, The Umbrella Academy is giving fans a little hint into some of the show's Easter eggs. This week, the series revealed that 43 sparrows are hidden throughout season 2.

Both the number 43 and sparrow symbol are greatly significant in the The Umbrella Academy universe. To start, 43 is the exact number of "extraordinary" babies born on Oct. 1, 1989. As we know, seven of those children were adopted by Reginald Hargreeves and became The Umbrella Academy.

This next part is a spoiler for those who haven't finished season 2.

In season 2, an eighth "extraordinary" baby named Lila is introduced. This leads to the sparrow imagery found in the Easter eggs. In the last moments of season 2, The Umbrella Academy arrives back in the "present time," but soon learn things aren't quite what they seem. Instead of Hargreeves starting The Umbrella Academy, he created The Sparrow Academy. The latter academy features all-new members from the original 43 children born on Oct. 1, 1989.

The Sparrow Academy is part of the original comics created by Gerard Way and Gabriel Ba. However, they don't appear until the end of the third volume. Blackman recently explained why they decided to include the Sparrow Academy in the show early.

“I have a wonderful collaboration with Gerard and we talk a lot about where he wants to go with the different volumes of the comics," he says. "I had an idea for the end of this season, a little similar to what the Sparrows were. When I heard he was doing the Sparrows, I got super excited.”

So far, many fans have been pointing out the sparrows throughout the season. One viewer noticed a sparrow on The Handler's bath towel in one scene while another discovered one in Hargreeves' notes.
