1)if i use "piloting" to copy leadership from the pilot on the first turn, than on the 2nd turn as the active player ,can i choose to use leadership before the "piloting" effect ends?

2) if opposing character uses pulse wave on blackbird and a character brought out from "i have some time to help "ability, does my opponent score the points for KOing that figure?

3)can i use special objects and resource in the same force?

Please quote the effects in question.

No. The effect ends before your beginning of turn phase.

Points are not scored for characters brought in via IHSTTH. They are returned to the Sideline immediately once they take damage.

There is no limitation on playing Special Objects and Resources on the same force.
