[Solved] How to know why a package is being updated/installed

Hey, sometimes when I do pacman -Syu, I see some weird package being installed and I am curious which explicitly installed package is installing/updating it.

How do I so with pacman?

I know we can easily find out why an installed package is being installed, but what about before the package is being installed?

pacman -Qi is the correct tool for this job.
- Ah, it worked. I thought Qi only works for packages that are already installed. Didn't knew it worked for things that are synced as a new dependency of a package
  
  Dependencies are installed, they're just installed as dependencies lol
I believe Pacman -Si or -Sii [package name] is what you are looking for.

-Sii is reverse dependencies iirc
- also pactree [-r] would be quite useful
- From the pacman man page:
  
  -i, --info Display information on a given sync database package. Passing two --info or -i flags will also display those packages in all repositories that depend on this package.
- Oh, I didn't knew you can pass 2 is. I was depending on the tab completion from pacman, but I didn't see that it says you could specify i's
