panicked
patient
pleased

Explanation:

The phrase "in his element" means being in a situation where one is comfortable, happy, and doing well. In this context, since he is in a crowd of like - minded people, "pleased" makes the most sense as it aligns with the positive connotation of being in one's element. "Panicked" is negative and "patient" does not capture the positive feeling of being in a favorable situation.

Answer:

pleased
