Katie herself said Lena would not have talked to Lex or thanked him. She was very clear that she wanted this scene cut. Just like Melissa wanted the scene cut where her and William talk about Lena in this same episode. They both felt those scenes went to far
@magnumdorkus4222 So they both did a behind the scenes during the filming of season 6. Katie and Melissa were asked about the relationship between the characters during this season compared to season 5. They talked briefly about how we will see the bond grow during this season and they both will rely on each other. They were asked about scenes in season 5 and how they felt it would carry over into this season. Katie said that there were things that were filmed towards the end that were cut because it didn't fit where they thought the characters mind sets towards each other were. Katie said she felt it was important not to show Lena and Lex bond, that Lena was steadfast and single minded on her goal and when that goal failed, had no issue leaving Lex cause she never got attached. Melissa said she likewise felt that certain scenes (I'm assuming the deleted scene where Kara is talking to William about Lena and tells him that she thinks Lena is far more involved in things and she doesn't know her anymore) that didn't fit Kara's statement that she would always be there. I took this to mean that they gave input into the deleted scenes. Given that they both took part in the storyline for season 6, I'm guessing they didn't want those scenes from season 5 in because it would make reconciliation harder to believe.
@magnumdorkus4222 During other interviews they have both used the words "wink wink nudge nudge for the fans" when discussing scenes that could be taken multiple ways between Lena and Kara. Melissa is the one who recommended William gave a girlfriend and Mon El leave to the future for good, she said this during a Cameo fan paid video. She said this was a wink wink nudge nudge for the fans now that Kara's known interests were no longer options lol. Katie said that Alex questioning Kara changing time for a friendship was a wink wink nudge nudge for the fans. I always took this to mean they were both implying their characters most likely ended up together post finale lol
Because it went to far. Katie herself said Lena would not have talked to Lex or thanked him. She was very clear that she wanted this scene cut. Just like Melissa wanted the scene cut where her and William talk about Lena in this same episode. They both felt those scenes went to far
