OOC:
Hmm... I would say at the moment option B is more feasible choice due to a couple of circumstances:
Kobort is blocking the area right now, presumably doing likewise already for Turuko (assuming he even passes his save vs Paralysis on his turn) as Gilly wants to do for Mal. So she'd essentially have to squeeze past Kobort and Turuko in the narrow corridor. Then she'd have to grab hold of a dwarf wearing heavy plate who's currently being straddled by a ghoul, and then try and drag her back past Kobort and Turuko again. I think that would be pretty difficult to do, especially in one six second Turn.
IF Kobort and Turuko weren't in the way I think an argument could be made that Gilly could take a Move Action, and then use her other Action to make a penalized Strength Ability Check to left the larger dwarf in heavy plate armor, and then on her
next turn she could start dragging her back slowly (Encumbrance rules would have to be taken into consideration), assuming the ghouls don't get a piece of her in the time between the two rounds. But I think with Kobort in full plate holding back a number of ghouls while half-heartedly trying to drag Turuko back as well, all in a narrow 5' hallway, would just be too big of a cluster-fart.
I
do allow PCs to drop weapons on the ground and draw weapons as a Free Action, but stowing weapons in their appropriate scabbards/sheaths/etc. or looking for and picking up dropped weapons is a regular Action.
So if Gilly wants to drop her bow on the ground (Free Action), draw her sword (Free Action), and then Move 20' forward, Attack, and use the rest of her move to make a 10' Fighting Retreat, she would essentially dash past Kobort, slash the ghoul he's fighting with her sword, and then back up to the space directly in front of Bors.
I would also say it's worth noting that Gilly saw Maloria fall as a result of the Paralysis these things do, and also would have seen that once Mal fell, the ghoul seemed to ignore her and went directly after Kobort, who was next in line. As did another from around the corner. They seem to have little interest in dealing with already fallen/paralyzed victims, at least for the time being, being more drawn to attack those that are an immediate threat to them.
Or that's what it seems might be the case, granted you've only had a couple of rounds to get a read on them...
