- ventboy appearing alive after explosion
- no one noticing/helping child when he climbs on alliance transporter
- warning signs wherever child appeared
- dream sequences with oily shadows, whispers, shepard chasing ventboy
- shepard complains of headaches
- indoctrination codex entry
- white fade in/outs whenever something dream-like occurs
- anderson being nowhere near shepard during the beam run
- harbinger not shooting down the normandy
- remark about the citadel looking like collector's base (pulled from memory)
- shepard hearing radio comm even though his/her armor is gone
- ashley and kaiden bodies only throughout citadel
- 1 m1
- anderson being ahead of shepard even though you never see him
- shepard bleeding from the same place he/she supposedly shot anderson
- mysterious elevator ride up to the catalyst
- control cut scene associated with TIM, destroy with anderson
- gun changing before and after the destroy explosion
- breath scene in destroy, official shepard lives
- saren advocating synthesis
- TIM advocating control
- Coat's corpse on the Citadel (only seen with flycam though)
- "SO BE IT" (Starbrat obviously siding with reapers)
- Catalyst/AI using image of the kid (so they are messing with your mind, even in a literal POV)
- the discussion between TIM and Anderson being directed to Shepard (eye contact confirms this)
- Arrival DLC (Object Rho and especially dialogue with Harbinger saying sth like "Your mind will be ours!")
- the beam not killing Shepard, though it certainly is able to oneshot gunships
- the relay explosions start at the wrong place
- the rachni queen's description of indoctrination and the black tentacle things creeping across the screen in the TIM scene
- unlimited ammo after shepard is knocked down in beam run
- shepard's constant exposure to reaper artifacts
- no HUD in the ending at all, only other instance are dreams
- rana thanoptis registered case of indoctrination and description of her case very much like shepard's symptoms (and same length of exposure)
- shepard going from barely able to move to acting like she/he hasn't been hurt when going toward device
- vega asking about humming noise on the normandy
- Anderson looking at the camera and saying "They're controlling you!"
- Leviathan Seizing Shepard's mind shows Shepard on his hands and knees being approached by an entity pulled from his memories
- Some Shepards outright being struck by Object Rho, and being sedated for two days. Harbinger says "Struggle if you wish, your mind will be mine"
- Recurring nightmares are a symptom in the audio logs in Arrival
- Indoctrinated Prothean Separatists advocate control
- Indoctrinated Desolas Arterius advocates control and synthesis
- EDI telling you Reapers use peace treaty ruses to pacify people while they indoctrinate them
- Sensations of darkness and cold. Anderson says he's in a dark hallway, and Shepard says he feels like death
- All Crucible functions being activated metaphorically
- Shepard seeing things that undisputably aren't happening. Like TIM and Anderson activating choices
- Shepard's idle animated in ME2&3 is him looking around, acting paranoid
- Buzzing and Ringing prevalent in ME3's musical score
- Infrasound present in game
- Shepard hearing whispers, oily tendrils on the screen and shooting people against his will during the TIM standoff. The scene that follows this is not grounded in reality

- Control rods are labeled "End choice bad"
- The tendril effect is labeled "Reaper Indoc Blur"
