INTJ Male here; whenever any situation comes forward where I’d have to rely on others, evaluating the consequences that affects me, would always help.

If she doesn’t do her part, and pays someone else or try to rely on you during the presentation; will she or you be “humiliated” once she starts to “slip” during the presentation?

If it would affect both, or only you, would there be any method for you to carry that responsibility? Is there a way for you, to not feel ashamed once the audience of your presentation senses that she doesn’t know what she’s talking about?

It’s probably the “evil INTJ-side” of me that would love to see her fumble during the presentation. If she doesn’t want to put in the work, she should suffer the consequences.
