Zephyr can't hear anything being said - the voices are too small and the barrier for the Rift too powerful at the moment - but they can still feel a sense of empowerment. They're going to help. They're going to try to help, and that means Zephyr should try their hardest, too.

They write out another quick message.

Please be careful. The Rift is really mean and greedy. I'm going to try to let the others know I'm still working to get in. I really wanted the holidays to be good for everyone. I'm sorry.

There's more than one window and the door still. Zephyr's going to try to get the attention of all the people - their people - in the house. If they work together, they can overcome this... just like the shadows and fear.
