On many prominent accounts, moral praise- and blameworthiness depend on the quality of will an agent manifests in their action. This paper draws attention to a pertinent but overlooked phenomenon: the manifestation of commendable and objectionable qualities of will in an action at once. By showing that all the manifested qualities of will have an effect on the agent's praise- and blameworthiness (i.e., on their action's moral worth), it is argued that quality of will theories need to provide an account of this effect. An account according to which the manifested degrees of qualities of will cancel each other out and the praise- or blameworthiness is determined by the remaining quality of will is discussed and dismissed. Finally, it is argued that agents who manifest objectionable and commendable qualities of will at once are simultaneously both praise- and blameworthy for their actions. Actions can thus have ambivalent moral worth.

The Surprise Exam Paradox is well-known: a teacher announces that there will be a surprise exam the following week; the students argue by an intuitively sound reasoning that this is impossible; and yet they can be surprised by the teacher. We suggest that a solution can be found scattered in the literature, in part anticipated by Wright and Sudbury, informally developed by Sorensen, and more recently discussed, and dismissed, by Williamson. In a nutshell, the solution consists in realising that the teacher's announcement is a blindspot that can only be known if the week is at least 2 days long. Along the way, we criticise Williamson's own treatment of the paradox. In Williamson's view, the Surprise is similar to the Paradox of the Glimpse and, because of their similarities, both these paradoxes ought to receive a uniform treatment-one that involves locating an illicit application of the KK Principle. We argue that there's no deep analogy between the Surprise and the Glimpse and that, even if there were, the Surprise reasoning reaches a paradoxical conclusion before the KK Principle is used. Rather, in both the Surprise and the Glimpse, the blame should be put on other epistemic principles-respectively, a knowledge retention and a margin for error principle.
