Ok Episode 4 of Season 10 triggered me. Smallville reunion and all we get is one memory clip from season 1 when he first met Lana. None of the cast from older seasons was there and was pretty much teasing us SMH why even have a "Smallville reunion" then?
Lana can't be around Clark and is in Europe. Season 1 clip is not Clark and Lana's first meeting, it's just the first day of HS. Chloe is also on her own mission. Pete didn't graduate from Smallville, there's no reason for him to return to a high school reunion.
