Then one day
You're pushed down a well
And you feel your funny bone crack
When it all goes to hell
-Spock's Beard, "The Water"
I have no idea how Alistair is going to react to this. Making a pact with an enemy is unlikely to go down well.
Great googly moogly it's all gone to shit
Now Alastair is probably going to spend a few seconds in shock and denial. A good trickster would blast him with a confuse spell since he's already confused, it would boost the effect of the spell but uh
Grain isn't exactly a good trickster though. I expect Jinx's little foreshadowing prophecy to come to light soon...
