After Cassandra calls out to her mother and gains the guards' attention on their target, Gothel cuts down the bridge to prevent them from arresting her, while abandoning Cassandra as she takes off. The Captain tells Cassandra that everything is going to be alright as none of the guards will harm her and that she'll be safe with him. After they return to the kingdom the Captain adopts Cassandra and raises her as his own.

In his care, along with Cassandra's hurt causing her mind to forget about her birth family, the Captain taught Cassandra how to fight and the importance of following the law. As he didn't want her to become a trouble maker and being the leader of Corona's royal guards has the Captain being a bit strict and hard to please. She grows up wanting to be a capable fighter, and to serve as a member of the royal guards, and eventually Captain. Even though he has the power to grant Cassandra's dream, the Captain wants her to earn it. Despite being a strict man and doesn't do special favours for Cassandra, he does deeply love and care her. Along with using his connections to help Cassandra get a job at the castle.

Season One
When Cassandra sneaked Rapunzel out of the castle and over Corona's wall, she believed that she'll be able to do it without having to worry about her father finding out, until Rapunzel's long hair grew back and became worried that her father would send her to an nunnery once he becomes aware of the disobeying role she played in it. Even though both Rapunzel and Eugene agreed to keep that fact quite from the Captain.

Season Two
When Cassandra touched the Idol of Vershaftsbezeigungengien in "Happiness Is...", it gave her the vision of her father as they spare with each other while he is impressed with her skills. Since Cass wants to prove herself to the man who took her in and is the reason why she aims to be a royal guard like he is.

Season Three

He reunited with her at the ruins of the maze that Rapunzel and Eugene previously visited, where Cassandra lashes out at her father as she is angry at him for hiding the truth about Mother Gothel from her and was determined to not have anything else taken from her ever again. Along with him giving Cassandra orders to stand down, like she was a rouge guard under his charge didn't help matters, as Cassandra had also swore to never let anyone hold her down again or to hold back, no matter what. Due to her corrupted actions and words from their encounter the Captain could not recognize the girl he raised and was after finally able to see what Cassandra had become.

Believing that Cassandra's corrupt actions were his fault and became ashamed of it, he chose not to return back to Corona and somehow ends up on Trapei Island. Where he exiled himself there and during his time on the island he found away to grant himself a second chance to be a better father to Cassandra, by re-raising Cass through her young self that was created from the Captain's wish. Since then the Captain was able to find happiness on the island has he plays and spends all of his time with young "Cassandra", like she really is the real thing, without realizing that his desirer had him abandoning the real Cass through her young replacement, until Rapunzel and Eugene found him on the island. Along with uncovering how little Cass (who casts no shadow) came into his life, and since the magic on the island has a down side, the two ask him to undo his wish before the ugly side of the wish's magic unmerges to terrorize the island. Not wanting to loss his little girl again, the Captain tries to leave the island with young Cassandra while Rapunzel begs him to not turn his back on the real Cassandra who is still out there. The Captain didn't want to believe the princess's words until he realized that the Cassandra he wished for has no shadow and that Rapunzel is right. After finding the courage to say goodbye to the "Cassandra" he looked after on the island and undid the wish, he returns to Corona with Rapunzel and Eugene in hopes that they'll be able to find and bring back the true Cassandra they love.

In the prologue of "Flynnposter", the Captain has a nightmare of him fighting Cassandra where he shatters the Moonstone to which enrages her. After he woke up he realizes that he cannot face off against his daughter, and decides with a heavy heart to retire from his position; which he passed onto Eugene as his successor.

After Cassandra reveals that Corona's Captain of the Guards is her adopted father in "Cassandra v. Eugene", fans began to support their family bond. The familyship's support grew after "Great Expotations" and "Secret of the Sun Drop" shows father and daughter moments between the two. Along with "Islands Apart" showing another side to the Captain through the little Cassandra he wished form, even though the flashback scene in the season three episode reveals that the Captain might had treated Cass as a disobedient solider than the former child that he looked after, as it helped fans to understand why he made the wish before Rapunzel convinces him to not give up on the real Cassadnra. When Cassandra reforms in the final episode, fans began to believe that the former Captain had joined her as she tried to find her true self. As they look for it together and catch up on lost time.
