Captain the dilithium crystals have failed.
Scotty can you repair it?
It will be real tricky.
Go for it scotty.
Captain I can replace the crytals but it will take some time.
Scotty we do not have that much time, the Klingons have dripped frozen, and clogged the dispenser, if you don't do something fast we will have a neutral zone.
Captain I have power now(new water valve) but only impulse. You will need to wait till the system can come up.
Scotty I need all you can give me now, what is it going to take?
Replace the main filter and purge the system by adding liquid directly to the core reactor(ice mold), make sure the system is clean so the chillers can work all propah and send me a 12 pack.
