To identify the predicate adjectives in the sentence, we first need to understand what a predicate adjective is. A predicate adjective is an adjective that modifies the subject of the sentence and follows a linking verb. In this case, the linking verb is "remain."

To find the predicate adjectives, we first identify the subject of the sentence, which is "the charmer." Next, we look for the linking verb, which is "remain." Finally, we identify the adjectives that modify the subject, "the charmer," and follow the linking verb.

In the sentence, there is only one adjective that meets these criteria, and it is "calm." Therefore, "calm" is the predicate adjective in this sentence.
