This is how Merlina explains about the Scabbard/Reuniting with Wyldstyle and Batman (The LEGO Movie) goes in Ryan and the Black Knight.
[Merlina and her new friends walk side by side]
Sonic: Why'd you and Evil Ryan stop me? I could've taken him down, no problem!
Merlina: You do not understand. He cannot be wounded.
Ryan F-Freeman: Yeah. Like a friend of mine once said.
Crash Bandicoot: Who?
Matau T. Monkey: Miss? How come that knight can't be wounded?
Merlina: He bares the scabbard of Excalibur.
Sonic: Hey. Wait a second. I think I heard that name before.
Emmet: I think that is a cool relic.
Odette: Me too.
Sci-Ryan: Ma'am. Did you happen to see 2 LEGO characters from the LEGO Movie by the names of Wyldstyle and Batman, would you?
Batman (The LEGO Movie): [pops up with Wyldstyle]Relax, guys. We are here.
DangerMouse: It's Batman and Wyldstyle.
