We return to Kat's perspective. We pick up just after chapter 621. No time has passed
*Kat's thoughts*
[Lily's thoughts]
D.E.M.O.N.S messages

Kat smiled down at Lily who was radiating happiness. Despite Lily's desire to 'figure out' how Kat was sharing emotions she was in fact already doing it. In Kat's mind there was the equivalent of two doors. One allowed Lily's thoughts and feelings to flow in, while the other allowed Kat's thoughts and feelings to flow out. For Kat, she could already feel the happiness Lily was generating as it washed into her mind.
