BRIANNA FROM "DORK DIARIES 8" ACTUALLY HELPS MACKENZIE, THE WICKED WITCH!
Think about it! Brianna wanted to rule the kingdom and I have proof; first, when Brianna met Nikki, she told her that she knew how she arrived here, because she saw it on 'WhoTube'.
The people around Nikki told her that they didn't take any video, but photographs, so Brianna already knew it by Mackenzie.
Second, Brianna never appears when Nikki needs her. I still don't understand how she continues to do that job...
Last, when Brianna turns Mackenzie into a frog, her spell only lasts for 24 hours, not forever. I am sure that she plans to take over the kinkingdom when Nikki leaves and Mackenzie turns back into herself.
