Barry's wanted Iris for so long that he will let everyone know about it. At CCPN: "Hi, Iris' boyfriend" (Mostly the women turning their seats and seeing Barry coming in). At CCPD, Julian would be like "Ah, Goody Two-Shoes Allen. And the girlfriend." At Starlabs, Cisco would be "Okay, you two. Before you start making out, I made a special room with no cameras, but an intercom. Don't EVER go near the med bay or in my lab. Capice?" And the list goes on. LOL!
