S1E10 Come Out Wherever You Are

Sonia receives an invitation to a prestigious debutante ball, but first, she and her brothers, Manic and Sonic, have a crucial task at hand. Robotnik has created a sinister weapon designed to capture and roboticize resistance members globally. The Underground's objective is to seize this weapon and install a deactivation device before the brain is integrated. However, Sonia gets lost in thoughts of the upcoming event, causing her to falter during the mission. With Sonic’s support, she regains her focus, ensuring they complete their task while still getting to the ball in time.
