Rita still had a borrowed tunneling skill she got from a treasure chest back in Round 8 using [Repay].
It was the one that let her phase into the space pirate ship — [Shadow of Nothingness]. She grabbed it the moment the original user was ejected from the ground after the skill expired.
Rita timed her use of [Repay] based on the borrowed skill's 5-minute duration. Its 3-minute cooldown had long since passed, but [Snowy Summer], the skill allowing her to phase into the ship, only had 18 seconds left.
If she wasn't a treasure chest by Round 18, she'd have to borrow another skill from someone else.
At 8 minutes and 30 seconds into the game — Round 18 — Rita's body finally lit up with a pale golden glow.
This was the moment she'd been worrying about… and waiting for.
The second the glow appeared, she activated [Lonely Antenna Baby].
