I really think that Shinigami is gonna pull a Karai(XD sry, girl) and betray everyone. Think about it: she's Karai's close friend, so Karai obviously trusts her, giving Shinigami more power to the Foot Clan. Then she went ahead and REPLACED EVERYSINGLE FOOT BOT WITH HER OWN SOLDIERS. In top of it all, the members of the Foot Clan that were not robots have all left, not wanting to ally with Karai. So if Shinigami feels like taking over the Foot, she can do so with a snap of her fingers(literally) and each one of the new Foot Clan members will turn on Karai, giving Shinigami total Foot Clan control! Finally, I have a last piece of evidence: we all know that TMNT 2012 loves bringing back characters from other incarnations, or at least making counterparts of them. Well, who do you think Shinigami's counterpart is? At first, I thought it was Lotus Blossom, because they look so alike, and then I realized: it's not Lotus Blossom. It's Kitsune! Think about it: they're both shape shifting, hypnotizing witches that come from Japan and work for the Foot Clan! And in the TMNT Mirage Comics, where Kitsune made her only appearance in the TMNT canon material, she worked for Shredder, hypnotizing Leonardo so that he thought he was part of the Foot Clan! In other words, Shinigami may be working for Shredder, trying to take back the Foot Clan for him! YOU HAVE BEEN WARNED
