To me it seems a word game, as happens so many time with philosophers. What is meant by the words 'knowledge' and 'consciousness', exactly? Define them strict enough, and the paradox will evaporate. E.g. in this case, let's define 'scientific knowledge' the ability to predict the future, and to choose scenarios where a specific future happens. Science is then the process for generating scientific knowledge. Newton's theory, for example, allows us to predict the future of an object with mass, and choose ways to put such objects together in such a way that they end up in a specific place at a specific time in the future. In this case, Mary knows everything about 'Red'. This means she can predict what happens when something red interacts with something else. If she also knows everything about 'Mary', she can predict her own surprise at seeing something red. She can choose actions that make her come in contact with something red in the future. She can then still feel surprised at experiencing red.
