"she bolted".

Ifilmens officiella novellering framgår det att hon försökte < em> döda Flagga.

In an instant June was gone, only to be replaced by the witch. Flag hesitated a moment to remind himself that this person—the thing he was holding—was not the woman he loved. That only through a bizarre twist of fate or magic or something inexplicable, they were sharing the same space and time.
He showed her the bomb and pointed to a button on the detonator.
“Once you put it in place, just push this button and drop it. It’s set to explode in two seconds. That should give you time enough to poof your way out of there.”
Enchantress smiled at Flag, not wanting to let him go.
“Darling,” she said, “I’d like to show you the world.”
“Seen it. Not impressed,” he said, calibrating the bomb’s timing mechanism. “Okay. It’s ready. You can take it.”
Enchantress only laughed. She leaned in, gave him a kiss, pressed the button then disappeared in an instant…
…leaving Flag holding the armed bomb.
Two seconds.
That was all he needed.

Hur som helst, orsaken Flaggan och de andra var i tunneln var uppenbarligen att döda Enchantress bror som var direkt ovanför dem.
