past tense or subjuntive mood

Saw this in a Taiwan Yahoo English Forum:

If you don’t have a story to tell then you might as well fail that assignment because whatever we gave you isn’t yours and it’s considered plagiarism. If it’s your homework, DO IT YOURSELF.

Whatever we gave you, is this a subjunctive mood? If so, how about this:

Whatever we would give you isn’t yours and it would be considered plagiarism?

Thanks.

As written, “gave” appears to be ordinary past tense. If “whatever we gave you” is supposed to be describing a hypothetical action then the last part of the sentence should read “whatever we give/gave you wouldn’t be yours and it would be considered plagiarism”.

“whatever we would give you” is not natural when talking about a hypothetical case.
