Who suffers extra damage 1 round later with Sticky Bomb.
The first sentence seems to imply anyone damaged by the bomb takes damage again one round later. I read it to be that those in splash area would be affected as well.
After the first sentence it only refers to a creature hit by a direct hit. Unless it is only referencing that to clarify that they take only splash damage the following round rather than full direct hit damage.
"Sticky bomb: The effects of the alchemist’s bombs are
persistent and continue to damage creatures for 1 round
after the initial damage. Creatures that take a direct
hit from a sticky bomb take the splash damage 1 round
later. Bombs that have effects that would normally occur
1 round later instead have those effects occur 2 rounds
later. An alchemist must be at least 10th level before
selecting this discovery."
