We're really sad to see the best TV show ever coming to an end, but at least we get to see some familiar faces one last time!
CSI is currently taping a special two-hour series finale to wrap up the 15-season crime procedural. The show has shot over 300 episodes, but in recent years, quite a few had been sorely missing some of our original faves from the Las Vegas Crime Lab, including Marg Helgenberger, who left the show back in 2012.
In addition to Marg, who played Catherine Willows, William Petersen – AKA CSI boss Gil Grissom — had quit the drama after season 9.
But now, the gang's all back together!
The Under the Dome actress took to Twitter to post this precious pic (above) of herself, William, and former castmates Jorja Fox, Eric Szmanda, and Paul Guilfoyle!
She captioned the sentimental shot:
"#OGCSI Great fun today with this gang!"
She also uploaded a sweet snap of her and William that made our hearts melt, considering we've not-so-secretly wanted their two characters to get together since the pilot.
Ch-ch-check it out (below)!
