- So what, you built a ray gun?
- It's not a ray gun,
it's a weapon that can deliver megadoses of photon radiation--
the same kind of radiation
typically administered to cancer patients.

- My theory is that these photons could be strong enough
to destroy Ramsey's sentient infection.
If I get close enough to blast him,
he should revert back to his human form.
He'd still have HLH,
but at least he wouldn't be a gooey zombie overlord anymore.
