Throw the phone at him then push past

Surprising him worked last time, so you try it again. As hard as you can, you launch his phone straight at him and start to charge.

"Nice try" he says, casually catching the phone in the air. The only surprising thing was how feeble your throw was.

Still hurtling towards him, you commit to the charge, but swiftly find yourself knocked on your ass as Jack braces himself and lets you bounce off his shoulder.

"Fine, this isn't what I planned, but I'll still have fun" he says, winding up a fierce punch.

"Wait!" you cry, but it's no use. He hits your square on the jaw and knocks you out cold.
