Why is the episode "Chaos Rising" they were able to use this ice technique to recall Isaac's lost memories with no consequences. Yet, now Deaton is telling Scott, Stiles and Allison they need to do this other technique which has multiple consequences; they could die, they will forever have a darkness around their hearts and it will draw even more dangerous supernatural beings into the area.

Would it not be plausible to have either Peter Hale or Derek do the same thing Isaac did in "Chaos Rising" to recall their lost memories that were taken from them and then get everyone to go in?
