Will it really be "Child's Play" for Rick Castle on Monday night?

When a second grader may be the key to solving a murder on the next new installment of this ABC hit, Castle goes undercover to figure out the identity of the student on Castle Season 7 Episode 4.  

However, will working with a room full of grade school students be too much for even someone as confident as Castle? We have faith in Castle - let's face it, not all men can pull off wearing fairy wings at work - but still.

Kids can be dangerous. In an adorable way, of course. Most of the time.

Check out these photos from "Child's Play," which is scheduled to air on Monday, October 20 on ABC. Get an idea of what's on tap:
