She wants to crossover to Lois

"I want to f... um, I want to see where this exchange with Lois leads" a blushing Kara waves the phone around, the picture of Lois pussy easily distinguishable.

Blaze nods and reaches a hand into the portal, which flickers momentarily before looking much like it did before.
"You should be aware, this is not one of your parallell Earths, this is a world that might have been, but didn't, a low probability contingency, a flimsy decimal place dimension in between the solid whole number Earth's you've gone to before.
When you cross over there, you will no longer be on your own home ground, you will be on theirs.
In fact, you're not really fully there, but instead being swept along in the current of their lives, you might at times change the course of things to some degree, but by and large, they are in charge."

Turning fully towards Supergirl Blaze asks "Do you understand? Do you still want to go?"

'That sounds... both safer since I'm not really there, and really effing risky since I'm not in control... which kinda sounds intriguing in it's own right... it's just for 24 hours Kara, and... well... that was a really nice picture Lois sent...'
"I understand, I still want to go, see you in a day I guess" nodding to Blaze, Supergirl walks confidently and quickly into the portal.

Blaze chuckles a bit as she watches Supergirl vanish as she enters the portal "I will see you in a day indeed Supergirl, of course, how long a day on your own Earth will be in the world you've now entered is anyone's guess, minutes, days, centuries..."
