Does Ada Wong's Level 1 ability trigger Infected text?
Ada Wong's ability allows her to look at the top card of the mansion deck, and either leave it on top, or place it on the bottom of the mansion deck. Although the rule book is unclear about a lot of aspects of the game, I don't think it is unclear what to do about Infected with Effects. The rules say that if an infected is revealed and it has an effect, take note of it, and apply it when the effect says so. Ada Wong's ability allows her to look at the card, not reveal it (a specific game term, that would make the top card open information), so no effects are triggered. I can also be determined from the rules, that only after revealing the top card of the mansion that you either defeat the infected and add it as a decoration to your character, or not defeat it is placed on the bottom of the mansion deck. So, any infected effects that trigger on not being defeated would only do so after being revealed.
