Does Kellan, the kid trigger off of the adventure section of a card?

So if I have Kellan and aquatic alchemist (using it as an example) on board and use the bubble up sorcery from aquatic alchemist, does this meet the condition to trigger Kellan as it was not played from the hand since aquatic alchemist was already on the board? Only asking since I'm hoping to include this mechanic when building the deck.
