Gwen's reaction to Monokuma exploding left her shocked, she looked at her palm where she was holding Monkuma and watched the new Monokuma arrive," What the crap ? I almost died, Who the hell makes a self defense program for a machine that makes it blow it's self up and take who ever is nearby with it ? That's an idiotic design, you would most likely cause friendly fire killing yourself and leave your allies short handed till you came back, who ever built you should have thought of a better self defense thank blowing yourself the hell up." Gwen explained to Monokuma and to who ever was listening. 

Nika watched as Monokuma exploded, the air from the explosion blew around some of Nika's hair and rung the erring bell that she was wearing making a jingly sound, she was shocked by Monokuma's explosion like everyone else, she stayed quiet and watched everyone else's reactions to when he exploded and was glad that she and some of the others could talk Gwen out of holding Monokuma for too long or she would have been blown up along with most of them.
