Due to the distances involved, Guran is going to have to throw something if he wants to attack. About the only other thing he could try to do is to hide; but he's glowing violet light, so that wouldn't work.
Guran's full move is 25 feet, but neither that nor a 20 foot move would put him near enough to "E" (in R35) to attack at range without disadvantage. (Guran has no javelins. His only ranged weapons go 20 feet before requiring disadvantage due to distance.) What he can do (unfortunately) is get in everybody else's way by stopping in the intersection, adjacent to kobold2. He might have a 25% chance to hit something with a ranged weapon at that distance, but it might be better than not attacking at all.
Because Guran won't get to act until Init 10, along with Spec and the Crone, I though I would take this opportunity to list a few of the (infinite number of) things that he won't be saying this coming turn.
(1) "I'm PURPLE! That's going too far, you foon: you have violeted my integrity!"
(2) "You have NAURed your last NAUR--Segolene Impf-Snade!"
(3) "Certainty of death? Little chance of victory? What are we waiting for?"
(4) "The elf, thereupon, did a perishing thing: she choked on her spittle and died."
(5) "Eat axe-bit."
(6) "Bogga-Wooga Fonz-Gwong!"
