Irori would not mind more information about Carissa Sevar, Himself, if anything has come to Abadar's attention about her.
Irori proposes a full trade of everything they respectively know that seems relevant, with Abadar not to use any information from Irori to hinder Carissa Sevar along her Way. If there is an asymmetry in the gains from the traded info, then they shall be reconciled by standard payment scaled-down for their mutual exhaustion (from the Zon-Kuthon war; their divine resources are now both more costly and more valuable to either of them).
