As Supergirl flies off to find the missing Kelex/Oscar, she says "J'Onn and I will find Oscar...." but J'Onn turns back to the computer station and crosses his arms to watch Brainiac and Zor-El work, and reminds Kara that there is kryptonite in the trash gyre, as if he has no intention of joining her in the search.
Kara's face is visibly puffier, especially apparent in close-up shots, and her whole physique not as lean and toned as in previous episodes.
