Melissa Benoist and Grant Gustin Bring ‘Supergirl’ and ‘The Flash’ Back Together in Paris

Every superhero fan has a crossover they still talk about, and for plenty of DC television viewers it’s the day Kara Danvers met Barry Allen. In “World’s Finest”, Gustin’s Flash shows up from a parallel universe just in time to help Benoist’s Supergirl battle Silver Banshee and Livewire. Getting there wasn’t easy, since it took some schedule juggling to get Gustin to Los Angeles twice during ‘The Flash’ production. That history is why any Melissa Benoist and Grant Gustin reunion immediately gets fans talking.

The 2 shows kept finding reasons to cross over. Benoist’s Supergirl reunited with Gustin’s Flash for a 2-part musical crossover that pitted the heroes against Music Meister. It doubled as a nostalgia trip, since the 2 were part of a mini ‘Glee’ reunion alongside Darren Criss.

Benoist told USA Today at the time, “I’m used to wearing a cape, and Grant is used to being in the cowl.” She described the musical as a refreshing change of pace for both of them. It also showed how well the 2 leads play off each other.

That chemistry is now back in the spotlight. Benoist and Gustin reunited on Saturday, Nov. 14, at the WTTM event from Dream It Conventions in Paris, with a short clip from the weekend showing the pair chatting in front of the organizer’s backdrop. Their meeting comes years after ‘Supergirl’ aired on The CW from 2015 to 2021.

WTTM stands for Welcome to the Multiverse, a multi-fandom event scheduled for November 14 and 15 in Paris. Gustin is listed as a guest alongside Benoist, and the ticketing page even offers a “Super Friend” duo photo option for Gustin and Benoist, where 1 ticket covers 2 people and 1 photo.

Benoist isn’t the only familiar face on the guest list. Chyler Leigh, who played Alex Danvers, joins Benoist and Katie McGrath for the weekend. The organizer also promoted stars from ‘Smallville’, including Tom Welling, Kristin Kreuk and Erica Durance, turning the convention into a wider celebration of DC on screen.

For attendees, Benoist’s schedule is packed. She is taking part in solo and duo photo sessions with McGrath, autograph signings, selfies and a Sunday meet-and-greet. There’s also a Supergirl group photo featuring Benoist, McGrath, Leigh and Chris Wood.

The timing is interesting, too. When Benoist’s appearance was announced, the ‘Supergirl’ movie starring Milly Alcock was making headlines with its theatrical release, and Dream It Conventions chose to honor the television version of the Kryptonian heroine. For fans who grew up with Benoist’s take on Kara, who played the hero for 6 seasons, that’s a welcome nod.

Benoist has long spoken fondly of working with her fellow DC leads. Around the time the series ended, she reflected on her favorite Arrowverse crossover memories and said she’d love to appear on either ‘The Flash’ or ‘Superman & Lois’. One outlet even argued that the first crossover helped widen the scale of the Arrowverse and showed an instant chemistry between Gustin and Benoist.

That’s what makes a simple convention meet-up feel bigger than it looks. The cape and the cowl are long gone from weekly television, but the affection between the 2 stars clearly hasn’t faded. Seeing Supergirl and The Flash back together, even in a convention hall instead of National City, is a reminder of why fans loved the pairing.
