With what the theme of s4 seems to be, I really wish Bizarro had a reaction to Jon, and it would have given him an important reason to be in the scene (instead of the reasoning being "so Jordan can tell Candice the secret off screen"). They didn't need any flashbacks to Jon-El, just have Bizarro break focus from Lois while she's talking to look at Jon behind her, zooming in on him. Seeing Jon makes Bizarro's expression soften and he makes a sad noise before stepping forward, reaching a hand out towards Jon. This makes Lois panic and step in front of Jon, pushing him away. While Lois is telling Jon to fly them away, Jon's gaze is locked with Bizarro's and understands what he's actually doing, asking to do. Jon knows what happened between his and his father's doppelgangers. Lois protests against Jon's decision to get closer to Bizarro but Jon tells her to trust him, so she does and Jon let's Bizarro rest a single finger against his cheek and cry. He misses Jon-El and Jon lets him see his son again.
