Problem number one--

Yeah, that's right. How did you know that?

But you guessed right.
Eva used Ramsey's blood

Unfortunately for us, without a replacement

So that brings us to problem number two--
[chaotic chatter]
- Quantum entanglement from reversed Higgs boson particles
disrupts the geospatial algorithm,
preventing us from locating people in the Mirrorverse,
meaning we have to know Kamilla, Singh,
and Iris's location in order to pull them out.

Ramsey's unique cells created a polar covalent bond
with the molecules in Eva's mirror portal.
That's why she needed his blood.
- Right, it formed, like,
a bio-friendly skin on the interdimensional barrier.
- So we need Ramsey's blood. We knew that.
- No, we don't need it. His blood would have bonded
with the electronegative particles
and become dark matter photons.
Those particles wouldn't just stay on the mirror portal.
- No, they wouldn't.
They'd attach themselves to Eva.
Those photons are still on her.
If we could collect them, we could open our portal.
But it would take, like,
years to develop a prototype that could do that.
