The Flash Season 2: 28 Easter Eggs & References You Might've Missed
16. Speed Dial
When we see the home of the West-Allens, because Iris and Barry are married on Earth-2, we get a close-up of their phone. Normally that wouldn't be very significant, and indeed the bigger point here is the message left by Barry's mother, meaning the Earth-1 version gets to hear her voice, but the Easter eggs come with the Speed Dial list.
After 'Dad' and 'Mom & Dad' (do you need both of them on there?) you've got Eddie - a suggestion of Eddie Thawne, still alive and a close friend of theirs on this Earth - and then the biggies: Bruce, Hal, and Diana. As in Bruce Wayne, Hal Jordan, and Diana Prince. As in Batman, Green Lantern, and Wonder Woman!
