Once Les realizes he's trapped on the Boardwalk and there's a good chance whatever's going on, is affecting the whole town, he thinks of April. The signal on his cellphone is down, but he casts a spell over the device to open a line of communication to April and just hopes she gets his messages, knowing she probably won't be able to answer him.

The power is out everywhere, isn't it?
Trapped in the Haunted House with Corry. We're fine.
Stay safe ok? When I get outta here, I'm making a heroic rescue. Or you come rescue me.
See you soon...
