'Is it gone forever?' He asks. 'Sadly, yes,' He walked towards his boy's bed. 'Dammit, Xander!' He says. 'How could you be so stupid!' He yells. 'I do love how you saved my life,'

'I wish it was me! I wish I was like this,' He tucks his boy in. 'I love you, very much, wake up soon,' He kisses his boyfriend. 'Do it for Daddy,' He kisses his forehead.
He saw Xander wake up. Wishing he could see William's face; 'Baby, I wanna see your blue eyes,' He said. 'I wish you could see our new house,'
