as other posted earlier , it character development .... they put a mini recap of 16 ( What the heck...) Cui aggressiveness , The twin wondering why there feeling this way and of course Yui-hime dere-dere mode
while little is shown, but F 22 has the edge on anti TSF warfare ... shealth is factor , so are units specs and plus pilots ability .... That's for now ... Cui unit lasting 4 minutes is respectable considering she's using TSF that has no stealth ....
