A 10 year old working walkie talkie?
I do like the movie and the screenwriter did a good job but come on, surely he could've thought of a more plausible way to establish a connection between the characters, for instance, Gabe visiting his brother and Shaun picking it up. What are the odds of Zach keeping the walkie talkie turned on if Gabe was off to college and hadn't used his in years?
