Dask may take appearance of excisting magic competition participant (Dask's paranoia forbidding from contest as herself), then contest is won by Aramis but then Dask (who had taken contestan clothes/lottery ticket) wins Delaiah and goes pick her up. Maya may out of curiosity follow Dask (something in fight felt off or such or knew by reputation the guise Dask used and magic not matching up), then notice Dask discard guise and take Delaiah with whatever form Dask usually uses in 'public' so to speak.<br/><br/>Then Maya knows Dask is changeling and that be connection dot between the duo.
