How do his inner conflicts reflect the overall conflict that builds in Act II?
In Act II, scene 1, Brutus soliloquy reveals his inner conflict as he grapples with his decision of whether or not to join the conspiracy.

Inner conflict is normally known to be an internal struggle. This means that the character is unsettled and does not have inner peace because of something that he knows or may have done. This inner conflict is showing through the various actions that he creates which can lead to the outer conflict.

This does not only happen in stories though although the conflicts that people experience are all different. There are moments when people can barely sleep at night because of their conflicting feelings and emotions. Take note that the outer conflict may sometimes not affect just one person but some groups of people all at the same time.
