Sunny Starscout is the New Element of Laughter · 3:11am February 10th
So, the inexplicable little roll call sequence from the recent Tell Your Tale episodes assigns virtues to the G5 Mane Six.
Sunny has Hope, Zipp has Bravery, Misty has Heart, Hitch has Kindness, Izzy has Creativity, & Pipp has Confidence.
Even if you're not paying attention you will notice that Hitch's trait, Kindness, matches up with Fluttershy's Element of Harmony.
However, this is not the only G5 trait that matches with a past G4 element: Zipp's and Sunny's traits match up with the stated Elements of the Pillars of Equestria Flash Magnus & Somnambula.
Therefore, since Somnambula was the Laughter equivalent of her group with Hope as her Element, then Sunny also having Hope as her trait makes her her group's equivalent to Laughter too.
If I had to equate the traits that the G5 Mane Six state for themselves with the G4 sets of Elements, keeping matching things the same, I'd do so as such:
Hope = Laughter = Hope
Bravery = Loyalty = Bravery
Heart = Magic = Sorcery
Kindness = Kindness = Healing
Creativity = Generosity = Beauty
Confidence = Honesty = Strength
(Note: This observation is more for fun rather than serious, but I do think it'd be a good thing to stick in a fan fiction or something.)
