I have a few more doubts.
The next morning (Can you say "on the next morning?)
We are being showed (is is a mistake or "shown" is correct?)
I waited for her to prepare/get ready (Are both possible?)
No, you wouldn't use "on" with "the next morning."
Use "shown" when it's the past participle (used as an adjective or with an auxiliary verb); use "showed" for simple past tense.
I wouldn't use "prepare" unless she was preparing SOMETHING (and that doesn't include herself!).
