Using the same spoiler pic for 2.23, of Barry and Iris kissing on the front porch but taking the moment a bit further into the future.

She expects him to follow her inside the house but he doesn't. Surprised, Iris looks back and sees Barry still standing on the front porch, staring out into the street. As she watches, he sinks down to the top step.
The screen door opens with a squeak of metal when she pushes against it. "Barry?"
He doesn't answer but she sees the furtive swipe of one hand against his cheek and her heart melts.
"Baby …" She squeezes his shoulder and sits down beside him. "Are you okay?"
He shrugs; when he slants a glance toward her, she sees the glimmer of tears still shining in his eyes and he sees the gentle, understanding smile she doesn't even try to hide. They both laugh, even though it's at his expense.
Iris pats his knee with exaggerated - but loving - sympathy. "Maybe you should have gone to work today."
"And miss their first day of school? Not gonna happen." The waterworks have dried up but Barry wipes at his cheek one last time and looks down the street as if searching for the small yellow school bus that carried his children away. "You know, I was thinking …" He tries to sound nonchalant but Iris isn't fooled. "What if I paid a surprise visit, you know, as the Flash? I could just … pop in every once in a while."
"I think that would make a bunch of kindergartners very happy - and if you make a habit of showing up to visit the twins at school, your secret won't be a secret for very long." Iris attempts to be stern but the sweetness of her emotional husband overcome with his feelings makes it impossible. She pats his knee again. "They'll be home at one o'clock. Think you'll be okay 'til then?"
He knows she's laughing at him - again - and laughs with her. Again. And then he grows serious.
"Thank you."
She picks up on the change in tone. "For what?"
"For them. For this." Barry's head tilts toward the street and the long-gone school bus, and to the house behind them. Then he simply looks at her. "For being Iris West-Allen."
Now it is Iris who wipes away tears. She leans in for a kiss.
"Who am I to fight destiny?"
