hen an ice cream vender is shot, evidence leads Beckett and Castle to believe that an unknown second-grader may have vital information about the case. Castle goes undercover at an elementary school to try and identify the second-grader but nothing goes as planned.
Overall, this episode was well-rounded. It had a little bit of everything for the Castle fan. It was good to see Castle with kids—no doubt this will probably spark another discussion kids in the future.
