Flickering Advance will get Mouse there fine, but it costs an Effort for the scene (remember more than one in a scene will start showing your anima banner).<br/><br/>Veiled Step means Talion won't be noticed unless he draws attention to himself or gets close to someone. If someone is a worthy foe (they have 3+ Hit Dice), they can make a Spirit save and if they pass, they have the normal chance of noticing you. They're not actually aware they made the save if they don't detect you.
