Kudos and adulation's oh benevolent cat god
Considering that my predictions and conspiracy theories are pretty much always completely off mark this is probably not whats going to happen, but, the whole food thing + Erica discarding her flesh body + teddy bear scene makes me think that:
1. Erica is going to lace her body with crysta mortem.
2. Erica is going to hug the tedy bear without letting it go so that it will stay with her body when it gets interred into the Katakomben.
3. Keun is going to be given responsibility for handling Erica's body and will discover a weapon and a pen inside the teddy bear.
4. Tariq and the rest of the Hexenhaus will consume Erica's body.
5. Keun will get discovered while trying to open the external gate.
6. Tariq will confiscate the pen and conclude that it must be a signaling device Keun is supposed to use once he unlocked the external gate.
7. Tariq and the rest of the Hexenhaus will prepare an ambush at the external gate.
8. Tariq will activate the pen...
Meanwhile while Erica will be unconscious from cyborg surgery, Tariq will send agents to dispose of her due to her being a collaborator of Keun and Yoko will do Yoko coolness and defend her defeating Tariq's agents.
Edit:
Thinking about it some more, Yoko's role being limited to defending comatose Erika would be somewhat lame, and Tariq being offed by crysta mortem would also be a bit dramatically off.
Instead maybe Yoko would be sent with Bjorn as the (disposable and deniable) support team.
Bjorn would have to deal with some other Hexenhaus that would not be taken out by the crysta mortem.
So Yoko and (goofed down) Keun will have a climatic battle with Tariq.
