Jack took the helicopter as soon as everyone got on board. He also witnessed Melony's transformation and included her in the following plan.

"Al, listen carefully! We cannot approach an out of control Allen! Do not engage closely, or the exposure to radiation can be fatal! Divert his attention from the air and try to direct his attacks to the air to minimize collatreal damage! Low intensity fireballs should do the trick! I am counting on your mobility to avoid his attacks! You with the sniper, I hope you can shoot around Allen so you can raise dust and limit his visibility! Sky, use your powers to disrupt Allen's senses with high pitch sounds! Apache-girl, I am counting on you to be our eyes and prevent anyone from coming anywhere near a 200 feet radius! Rowan, I want you to create a block of lead around Allen while the others distract him to suppress the radiation for as long as you can so I can get close to him and get him to reason! Do not forget, he is a friend! Do not harm him!" Jack said through Sky.

It was the best plan he could come up with and hoped it would work, if the others didn't mind following it of course.
