Not sure how to translate about the first bubble on the second 4koma.
What "かけておいた" means at the end?
Also, need a check for the rest of the translation.

Adding the verb 置く after the stem form of another verb conveys the implication "to do something in advance/ahead of time", though that sometimes remains merely implied in translation as well.
