Vampire Diaries star Ian Somerhalder (Damon Salvatore) has been bringing it back — way back — for Throwback Thursdays, gracing us with photos of Damon from flashbacks past. Last week, it was Civil War-era Damon. This week, it’s equally swoon-worthy World War II-era Damon.

“Technically a #throwbackthursday it's Thursday in many places!” Ian captioned the Instagram pic of himself as Damon looked handsome in uniform. “Damon Salvatore circa 1942 New Orleans Louisiana.”

Lately, Ian seems to feeling nostalgic for Damon flashbacks — maybe this implies another Damon flashback on the horizon? TVD could do with some more flashbacks. And the WWII-era flashback in Season 4, Episode 8 (“We’ll Always Have Bourbon Street”) was one of our absolute favorites. In it, we see Damon, Stefan, and Lexi kicking it in 1940s New Orleans. Stefan is doing better in controlling his Ripper side, and Lexi convinces Damon not to join Stefan in enrolling for the army. It is actually pretty heartbreaking as Damon shows up at the train station (as seen in the throwback pic), ready to go, only to have Lexi (Arielle Kebbel) intercept him. Stefan leaves for war thinking his brother selfishly ditched him, when really Damon was not going for him. The angst!

Last week, Ian shared this Instagram selfie of a serious-looking Damon in 19th century garb as the sun sets in the background. “#throwbackthursdays Season 1 Damon at his house in Mystic Falls — Circa 1864,” Ian captioned the pic. It’s hard to decide whether we enjoy seeing the Brothers Salvatore more in the Civil War era or World War II era — both glimpses into the past reveal so much about these characters.

Which flashback era do you prefer: Civil War or World War II? Sound off in the comments below!

The Vampire Diaries airs on Thursday nights at 8 p.m. ET on The CW.
