Season 5
BLOODLINES

Kolivan informs Keith they need to extract a Blade agent and destroy a super weapon created by Galra forces; which Keith will do on his own. He then shows Keith a surveillance image of the Blade agent – Krolia. Soon Keith leaves for her, making his way through a battle field. He infiltrates the ship she’s on. Keith makes visual of her, Krolia stops in her tacks, turning in Keith’s direction. Keith quickly hides back behind his corner. Moments later, she turns back and continues forward. Keith does to, only for Krolia to hold hold her gun to Keith’s head and Keith hold his blade to her neck. Keith says her name, then Krolia takes notice of Keith’s blade, she lowers her gun and tells Keith he’s late and that they don’t have much time.

Once inside, Krolia asks why Kolivan risked sending Keith in now. Keith tells her because it’s Ranveig’s super weapon. Moments later, the first layer of defense is breached. Krolia tells Keith they need to run, they make it to an elevator. Once exiting, they’re attacked by droids; they’re able to hold them off for a bit before Keith is taken down by Trugg. Krolia slowly stands and disarms her sword back into a knife. Keith watches on with a bewildered expression. She then holds up her hands and says to Trugg, “We can make a deal.” Keith then yells at her, “What are you doing!” Krolia turns he attention to Keith, saying, “I left you once; I’ll never leave you again.”

They make for a battle cruiser, once inside Keith is angry at Krolia for saving him; for jeopardizing the mission. Krolia turns to Keith and tells him to “shut up and trust me.” Following the deal she made earlier with Trugg - she gives Trugg the passcode for the super weapon. Once the code is confirmed, she and Keith fly off. Trugg orders a lackey to shoot them down. Keith flies them far away enough that they’re no longer being fired at. Keith goes up to Krolia, she gives Keith his knife back. Keith asks how she was able to use it – she then drops a bombshell on him; it used to be her, before she gave it to Keith’s father. Keith goes wide eyed, before saying, “You’re my –?”

Season 6
RAZER'S EDGE

The episode starts right where “Bloodlines” left off, with Keith finishing his ''“You’re my mom? How? How did you get to Earth? How- how did you meet my dad? How- how are you so sure?”'' Krolia says she's sure and goes on saying how this isn't how she wanted Keith to find out, but there are other important matters to attended to. Keith is frustrated at this, but he finally accepts that they'll talk later about it. They resume their mission.

Soon they head for the quantum abyss.
