"I had quite a bit of fun, even if a good bit of that's anticipation."

"Me too.  I'll be honest, I never imagined how pleasant doing this sort of thing with somebody else would be."

"It's the best part about a team! Both adding a social aspect and new tricks when our powers combine well."

"Indeed."

She'll head back in with a few simple parting words.

The next morning, something quite interesting has made the news.

"...reports from Williamsburg of two murders in one night, committed with no apparent witnesses.  At midnight last night, a woman was discovered by her husband, killed in her own bedroom; and this morning a second victim was found on the roof of his house.  Police have not released the names of the victims, but say that there is no apparent connection between them, and that they do not suspect the families of the victims of any foul play at this time.  Neighbors are shaken, and have expressed worry about the possibility of a superpowered serial killer in their midst..."

"Fun! Still a mere possibility..."

"That's how it always starts."

"I wonder how long it'll take them to start connecting dots."

"That probably depends on our next moves.  Speaking of which, do you still have that map?"

"Yes, let me get it..." She does so.

He'll spend some time poring over it with her, planning the order in which to kill their next victims.

They should try to make the final form as non-obvious as possible - while it's inevitable their last movements will be predicted, it's more exciting to stave that off.

And more strategic!  He'll help plot out the best order in which to kill their next victims.

She has some experience with this, and knows the head detective in the area very well, too, which certainly helps.

But, well, they can hardly spend their lives just planning.
