I don't have high hopes for whatever the resolution to Wanderer's arc will be and similarly I don't expect them to not fumble whatever plans they might have for Dottore
but the one (1) thing I do hope is that they reveal he and potentially other important personnel like Pierro and The Tsaritsa have countermeasures to get around the Irminsul memory wipes. Would be cool if he could just nonchalantly drop something he's not supposed to know like what Scaramouche did or everything related to Rukkhadevata
