her or she

Could someone enlighten me on why is used 'her ’ instead of ‘she’ in this sentence?

You people obviously haven’t read the ‘ellie chronicles’ because at the end [color=red]her and lee are together.

“her” is incorrect. It should be “she”. There are also capitalisation errors.

Thank you.And what about in this sentence is ‘her’ used correctly?

I think that her and Jack are dead.

That should be “she” too.

Got it.Thank you very much.
