Here's my take on the next episode: Jericho.
take place BOTH past (dykk talking to jason) and present day (the team)
5 years ago jericho didn't die. dyk thought he died but he transferred his conscious into Dr Light. thats why deathstroke broke him out... he really had no need for him.
once jason and beastboy snuck in... jericho transferred into beast boy and deathstroke then killed him. how else could deathstroke get into the tower and also BB wasnt in any of the pictures.
plus its convenient he was "sleep"
so while dykk is telling the story on the roof in the past .. jericho is doing stuff in the tower in present
then in atonement .. dyk learns to forgive himself especially for having guilt that wasnt warranted since jericho wasnt dead. and he embraces the fact he is like Bruce and he also is not like Bruce .. that births nightwing mentally or dyk
