8 Elements[]
There is a guess online saying that there is actually not only the 5 elements we know now , not only Air , Fire , Water, Earth and Ice but also with Sun, Moon and Lightning.
As we know the world of Tangled is connected with Frozen , if the Sundrop flower is the Sun element , well the opposite of sun is moon, so maybe there is a Moon element. Under this logic, the water element should have an opposite too , but what we know now it doesn't . So people make a guess that that is reason why the Nokk was aggressive , it lost its opposite , but Nature has to be balanced so it got aggressive.
The Reason of Elsa Being Locked[]
Some people think that the reason of Elsa being locked is not because her parents want her to learn to control her powers , but because they are afraid of her being caught . Elsa's power's were known at the age of 8 and Rapunzel was stolen not long after she was born , at that time Agnarr and Iduna would defiantly know that already , so under fear they chose to lock her for her safety.
Olaf[]
Olaf is made from snow and magic from Elsa , in "Once a upon a Snowman" , Olaf didn't know who was at first , but after he fell of the cliff , the sounds of Elsa & Anna's childhood time when they made him played in his head , and the he finally know who he is . But there is a problem here , Olaf was not alive yet , during Elsa & Anna's childhood , so how does even know that ? Also at the part he told the Northuldra and the Arendelle soldiers about Frozen 1 there are a lot of things that he shouldn't know , but he some how did. So maybe he is made not only from snow but also from memories of Elsa whatever Elsa has gone through , seen , done , he'll be able to know, in other words some people say he is Elsa's "son".
Elsa is Dead[]
People have thoughts that maybe Elsa is dead. All known , Elsa has become the official fifth spirit , and she has dead once but become alive again. But people notice that other then Bruni all the other spirits aren't really "living creatures" so how about Elsa , could she just be REALLY a spirit but not a human?
Mother Gothel is not dead[]
Mother Gothel the antagonist of Tangled , in the start of Tangled , it shows that Mother Gothel found a flower under a cliff and became younger with it , think back to Snow white the witch fell of a cliff at the end , but the movie didn't show she died . Hmm... cliff... , so could it be that Mother Gothel fell of the cliff and then found the Sundrop , then became Mother Gothel. Make sense , back to the ending of Tangled , after she fell of the tower , it neither showed her death but she once again vanished , in the Frozen 3 trailer picture , there is a black figure at the right down corner , it could be Gothel , maybe because she needs a new source of magic to stay young , she could be eyeing for a strong source of magic likes Elsa's...
Anna has Powers[]
People who watch Frozen always have a question : Why doesn't Anna have powers ? People then make guesses : Maybe it would appear in Frozen 3 , maybe she might face the same problem as Elsa did... Maybe her powers aren't visible likes Elsa but instead invisible , her power could be love how she can connect people together , and show love to anyone... Maybe she once had powers but were removed , in Frozen 1 , after Elsa hurt Anna , Pabbie removed all magic on Anna even memories , and maybe he removed Anna's powers unconscious.. well lots of guesses.
