Flashing on second part of Lee Sin Q
So apparently you can flash mid-way as Lee Sin and still retain the second part of your Q. For example: Lee hits a target with Q. He activates the second part and travels to the opponent. He flashes before the damage is applied, insecs them, then activates Q again to Q all the way back.
Saw it in a CellyBeary video; had no idea this was possible. It seems very uncommon.
