Sid's real name is Sydney
Ignoring the fact that Sid is a boy's name, she has a younger sister named Adelaide, which is also the name of an Australian city. Their mother could possibly be of Australian descent - she is also a zookeeper who regularly brings animals home and even manages a gator tour, perhaps a nod to Steve Irwin - which may explain the girls' names.- Confirmed about Sid's name, but her heritage on her mother's side is still unclear.
We could get a Fist of the North Star (or other type of Bruce Lee inspired story)-esque episode
After all, if Sid is confirmed to be a Chinese-American (we've already got a lot of minorities represented in the Loud House universe), so why not something different? We could also get a Race Lifted Bruce Lee Clone, as in this case, probably an African-American. Sid will become Clyde's new love interest
Once Ronnie Anne introduces Sid to Lincoln and Clyde, the latter will develop a crush on her (or vise versa). It helps that Clyde's Precocious Crush on Lori has been reduced in later episodes, and with Lori already in a relationship with Bobby, Clyde could also be paired with someone his own age. Plus, it would break a potential Third Wheel conflict either Lincoln or Sid would have to face around Ronnie Anne. The series' events take place between seasons of The Loud House.
This would explain why the Casagrande family members have yet to age up. For example, season 1 takes place between seasons 2 and 3 of The Loud House and season 2 takes place between seasons 3 and 4 of that show. Maybe season 3 will have the Casagrandes age up to tie in with the Loud family members aging up in season 5.- Coming to think of it, very few of the Casagrandes episodes are actually stated to take place during Season 5 of The Loud House. These episodes are "Cursed," "A Very Casagrandes Christmas," "Tee'd Off," and possibly "Curse of the Candy Goblin."
The reason Par is a thrill-seeker.
It may be that, just when Par was eager to start his own life, he came down with a serious illness that nearly took his life. After making a full recovery, he took on a new appreciation for life and devoted himself to living every day of his life to the fullest, from opening his own karate school to doing all these extreme stunts in his spare time.
