Not really, no. Adalind has never been at the center of things on Grimm. I mean…she’s been the cause of a lot, but she’s never been an integral member of Team Grimm necessarily. And the show is very much about Nick and his close-knit group of friends, so that has always made sense.
I mean, let’s look at Adalind over the seasons:
Season 1: Pops up every couple of episodes as Renard’s villainous secret agent. Her actions drive the lead up to the finale, but she only appears in eight episodes.
Season 2: Spends most of the season in Vienna. Returns to Portland long enough to gloat over Juliette’s comatose condition and get pregnant by Sean. She only appears in nine episodes.
Season 3: She appears much more in this season, in all but two episodes. However, her scenes are relatively brief and she is not in Portland for the majority of the season. Again, her storyline leads to the big finale, but it isn’t integrally tied to the rest of the team until she returns to Portland with Diana.
Season 4: She appears in 17 out of 22 episodes, and spends the first half of the season back in Vienna (her frequent flyer miles must be A M A Z I N G). She then spends the majority of the rest of the season with the Royals, trying to leverage her relationship with them to get Diana back somehow. She doesn’t team up with Nick and his friends until near the end of 4×19.
Season 5: This marks the first season where Adalind appears in every episode. She spends the majority of that time in the bunker with Nick, and is still not really a full member of Team Grimm. Whether because of their past with her or because she’s not interested or some other reason, Adalind isn’t along for most of their cases and isn’t included in key information…like the Stick of Destiny and what it does. She is separated from Nick and the team again in the penultimate episode.
Season 6: She has appeared in every episode so far except for “The Son Also Rises.” She spent the first episode separated from the team and most of the second episode doing what she could on her own to help them. She’s been included in the team’s activities more this season, but spends most of her time off-screen with Diana and Kelly.
So no…I don’t think it’s really that strange. In a way, it makes sense. In the past when we saw a lot of Adalind even though she was far away from Team Grimm, it was because her actions were building towards something that they were going to have to deal with. Now, she has pretty much everything she’s fought or searched for throughout the series: her powers and both of her children. Any revenge she wanted to mete out has been dealt, and far seeking more of it she seems to regret many of her past actions. The fact is…there isn’t an awful lot for Adalind to do on screen anymore, especially with four episodes left and whatever big bad is coming on its way.
Granted, I don’t necessarily like this state of affairs. Adalind was always so interesting as a villain, and now it seems like the writers just don’t know what to do with her. They rushed a redemption arc that didn’t make any sense and as a consequence rid Adalind of all the traits and conflict that made her interesting. The result is that we have less of her in the final season, and the few scenes we do have are relatively brief and don’t allow her to dominate the screen the way she did when she was bad.
