Gonna post my crack theory cause hehehe
Relisted to Fool's Gold: Sands and I paid extra attention to Marco after they got back to Teek(?) in the later episodes.
Felix described Paulina with the phrase "hence why she doesn't live there [the Underdark] anymore."
What other Drow do we know of that doesn't live in the Underdark anymore?!
Marco is described by Avery as "being so charming he comes across as suspicious."
What other Drow do we know of that's very charming and also very suspicious?
HERE'S WHAT I PROPOSE: Marco is Andromeda's son.
The story goes as follows:
~Once upon a time~ there were two Drow teens in love. Young love and they were starting to figure out life and emotions and themselves.
But then something in their city happened. An attack or raid led by a demon army under the banner of Abereth. Many died in the attack, either directly or from the damage caused to the city. Some were taken, some managed to flee, but most died.
The young lovers were separated.
Andromeda was taken by the army. Dragged deeper under ground than even most Drows usually ever go. But, he managed to survive. Eventually putting his old life behind him and focusing on his new life among demons. He managed to thrive, becoming strong and claiming a spot of power and authority in the very army that took him.
Paulina managed to flee to the surface. At first it was tough to adjust, and not just to the sunlight. But she managed to survive, and then through using her knowledge of potions, managed to thrive as a medic. But, when she fled from the raid, she didn't know that she was carrying a child with her. That only came to her knowledge during the later months.
The two young Drows never knew what happened to each other during or after the raid, presuming the other dead. Andromeda never knew about Marco and he still doesn't. Marco doesn't know about Andromeda, and he likely won't.
I'm also gonna shove my own DnD thoughts into this because yes. It's my crack, I get to flavor it.
Being able to use magic is a common thing. Not everyone can wield magic by themselves, many borrow from higher powers either through faith or deals. But, being able to wield magic is genetic.
SO MARCO GOT HIS ABILITY TO WIELD MAGIC FROM HIS FATHER, NOT HIS MOTHER WOOO YEAH BABEY
