Words have the power to change how people perceive reality and that's precisely what happened after Uriel and Sam settled their differences for good. Once Sam voiced out that he thought of Uriel like a brother, the system somehow recognized him as such.
This was a great deal for Uriel who had never experienced having a family before, the only memories he had of his parents were so distant and fuzzy they were more of an ethereal concept than actual parents.
However, something bothered him. The cyan liquid that dripped into Sam was much similar to the one that covered him after he stabbed himself on the heart and because of the short time he spent with Water warlock he knew that his flux energy was also cyan.
In the end, Uriel decided no to voice any of his concerns about Water warlock to Sam since he didn't know much himself and there was nothing they could do.
