Ada Wong tracked Leon for 6 months before RE9’s beacon cutscene. She defected from The Connections in 2024 after discovering the Marcus Halverson cover-up. Her radio beacon in RE9 NG+ Insanity unlocks the next phase of her arc.
| When | Event |
|---|---|
| 2017-2023 Connections work | Ada operates as Connections asset gathering Eveline-related intelligence. Trusted by leadership but secretly skeptical. |
| 2024 Marcus discovery | Ada accesses Vance’s cover-up files. Reads Marcus’s daughter’s name. Decides The Connections has become unethical. |
| 2024 defection | Ada leaves The Connections. Goes underground. Begins surveillance on Leon Kennedy (who has BSAA contacts). |
| 2025 Bulgaria investigation | Ada investigates Bulgarian Eveline reports. Gathers photo evidence (same photo that appears in Mia’s helicopter). |
| 2026 January | Ada determines RE9 events are imminent. Cannot intervene directly without exposing position. Decides to track via Leon. |
| 2026 February (RE9 events) | Ada monitors Leon’s RPD return remotely. Witnesses Mr. X transformation via remote intel. Plans extraction. |
| RE9 NG+ Insanity beacon | After NG+ Insanity completion, Ada activates radio beacon. Leon hears 3-word message before signal cuts: “Trust no one.” |
| RE10 prediction | Ada DLC almost certain. Director Nakanishi refused to deny Ada DLC in May 2026 Famitsu interview. RE10 will feature Ada-Leon reunion. |
This lore decode reveals layers of RE9 most players miss. Cross-reference with character profiles and other deep dives to build the full picture.
