Just in time

Amelia was thinking about what to do. She could not make odin's effect pass when they needed. There was no way to do this. The drug was already strong itself, his action was abnormally fast. If she tried to make it even faster, Alfar could suffer the consequences afterward, and Olaf as well. 

Besides, the collateral effects they were having weren't something to be canceled so easily. In fact, she didn't know if it was the most intelligent thing to force too much. The better way to go was to wait until the drug's effects passed at the right time, however, she knew that Casper wouldn't last long there. 

Even with all the controversies, she needed to find another way around, otherwise, Casper would be taken, and all those efforts, meaningless.
