I would say that the best summary is <span>Hyde drinks from the glass and begins staggering around. Lanyon watches Hyde’s features change and leaps back in horror.
This description would reveal how each character reacted one to the drink and the other one to the drink reaction. While Hyde experimented physical changes, Layon observed them in "horror".

Answer:
There have been many times where I felt uncertain as to how to act. Sometimes, it's because I have to make some kind of decision, and what I choose will have a larger impact. There are also times where I'm around people I don't know very well, and therefore don't know how they expect me to act. I would feel uncertain because I have no way knowing, without a doubt, what the right choice is, or how other people expect me to be.
