After Corrine sacrifices himself to save Sheena at the Temple of Lightning, Sheena becomes depressed. In one of the optional Z-Skits, the player sees that Zelos is still acting lighthearted, as if Corrine had not just died. He is then chastised by the other members of the party for his lighthearted approach. When they leave, Zelos remarks to himself that, if the party members continue being visibly upset, Sheena will only get more depressed, and will not move on with her life; the only way to help her get over the loss is for them to move on. Contrary to what one might assume, Zelos is actually very similar to Colette in some aspects. Both of them tend to bottle up any worries or insecurities they might be feeling and mask them with cheery personalities so that they don't have to deal with others in the party asking them is something is wrong. Both of them also have to deal with the consequences of hoarding such feelings, in that they suffer alone and they ultimately end up causing others in the party to feel guilt for not noticing that something was bothering them sooner.
