Quote from Excalibur;1028639:
You can give it to his ghost if you're doing season 2.
Well, none of my characters are set up for that sadly. Both my mains are finished S2E1 and my alts all haven't touched S2.
Could be worth looking into, but I doubt that Devcat would program anything in for something so specific such as being part way into S2E1 and done S1E3.
Does his ghost even hang around town during those quests? I always remember it as popping in during a quest dialogue/cutscene and then dissapearing.
Edit:
Worth noting that after a quick scan of the marketplace's consumable option. The following NPCs have chocolates.
Tieve
Seanna
Nel (with the amazing pun CaraNel)
Marrec
Gallagher
Dolores
Clodagh
Brynn
From a functional standpoint, Seanna, Tieve, and Clodagh are identical. Marrec's chocolate loses out to Dolores (100 Att vs 300 Att) and Nel's loses out to Gallagher's (30 Def vs 100 Def), Brynn's is the sole M.Att chocolate.
Not sure if you can give something to, say Nyle, and recieve like Brynn's. I'll test that tomorrow.
Otherwise that's probably the list.
Marrec's dialogue is just more Marrec x Caera fodder, if there wasn't enough of that. Nel's is just Nel being Nel. Seanna's not particularly interesting given that Seanna is well... Seanna. She was only relevant to Ep7 and post Ep10.
