I personally believe that Nova Curious is not Lazlo's kid but Vidcund's.
Appearance wise, sure some claim she is Lazlo's kid just for being dark skinned and having dark eyebrows but:
Lets remember all three Curious brothers are the sons of Glarn, who is medium skinned with black hair, same way Kitty is blonde and tan skinned (TS2 skintone names ofc).
So, Vidcund could have brunette children, same way Lazlo could have blonde ones.
Nova has medium skintone like Glarn, pressumably black hair while also having gray eyes like Kitty.
She is competitive and very ambitious considering the secret ending "Nova has it all" (Keeps the job, becomes an indie developer and falls in love with Lewis)
Vidcund was also the closest to reaching the max Logic skill in TS2, indicating that he was the "book smartest" of his brothers, Pascal and Lazlo are just 1 point in Logic.
Nova has 6 points in logic, 3 in mischief... Almost as if that indicates who her father may be.
Its almost as if she carried her father's karma. "Stuck in their shadow"
Vidcund is not as creative nor contacted with aliens to the point of being pregnant by them compared to Pascal; and despite being friends with his brother Lazlo, the younger Curious brother was higher in the Science career (Field Researcher - LVL 3, just needed one cleaning point to get yet another promotion) while Pascal and Vidcund were Lab Assistants (LVL 2).
However, Lazlo is always described as the most relaxed of his brothers (Which contradicts with his TS2 Sagittarious personality and TS4 trait "Ambitious"):
"Jovial and carefree, Sagittarians are also blessed with boundless energy. Unfortunately, this combination can make them restless and careless."
Considering as well that unlike his brothers, he didn't had a rivalry with Loki Beaker while Nova has a rivalry with Lewis, besides the fact Lazlo only became a scientist because of the monkeys.
When Lewis and Nova talk about their childhood, they mentioned being scolded by her dad for playing in his lab. Lazlo has 9 personality points making him playful, unlike Vidcund who has 4 personality points, making him serious. Lazlo doesn't give me the impression of be the scolding type in a lab, more of a "hey kids watch this" kinda scientist.
Vidcund is a Scorpio,his TS2 Personality and TS4 traits (Esp Loner and Neat) seem to align more:
"While somewhat withdrawn from social activities, Scorpios are forceful and determined in more practical pursuits."
So to me, it makes more sense that Vidcund is Nova father instead of Lazlo. Considering she hanged with Tycho in the past, it could mean Pascal and Vidcund were in somewhat good terms, still, Nova's bohemian style, to not highlight her tattoo are flowers, while still keeping her ambitious personality hints at how Lazlo and Vidcund are best friends and probably the reason why she has 3 skill points in mischief (Lazlo has the goofball trait), maybe helping her not to be as serious and grouchy as her father, and definetly way more than her uncle Pascal, maybe Tycho is wasn't scary for being an alien, but probably being as serious has his dad (0 personality points, making him super serious).
