Assuming he still can and indicates that it is ahead, she will continue to follow it with a double move. I'm thinking that Nev will catch it and she will simply assist once his strikes indicate where to aim.
If he cannot still see it, she will take an action to cast See Invisibility and then move to continue following it.
OK, I need to give Gil and Nev a view on the puckwudgie. It is running way at full tilt, invisible but not otherwise attempting to conceal itself. That means it's covering 120' a round. It's about 250' away now. Nev can cover that, and Gil can probably catch up, but it will be a separate fight effectively as you'll be leaving the others. So let me know what you intend - if you go in pursuit, you'll be going to spoilers.
Gil is at the mercy of the psychic warrior unless she gives up a precious move action to cast see invisibility. She might be better off casting fly, but then she can't see her target. I hesitate to get too far from the others for reasons that I hope are obvious...
How 'bout another Storm bolt? Ez aims it at the middle of the slab; along the way, it hits Students 3 and 5, plus the Lecturer. Damage 6d6=23 electricity, Reflex 24 for half damage. Can he use his Metamagic Mastery ability to amp up the stormbolt, or is it just usable on actual spells?
OK, he's not webbed but the web is still difficult terrain. Also, he can't see damn all from BF10 given the lecture theatre slopes down. So he can go with his original action. However, the guys behind the slab have total cover - you cannot really reach them with a Storm Bolt - so you can choose a different set of targets if you wish.

I'm looking at it; I'm sure he can hit S3 from BF 10.
If I draw a straight line from the bottom right corner of square BF 10, I can cross the squares inhabited by S3 and S2 without crossing the corner at square BI 9; this leads me to believe that Ez can hit both S3 and S2.
If this is indeed so, this is what I think Ez should do; I still think he should at least blast S3 if that is all that is possible.
"F$~& this. I'm taking the fight to them. Follow me if you can!" Janosz shoulders past the golem and runs down the stair, firing as he goes.
Move to BO 11. My route is BK11-BL10-BM10-BN10-BO11 (I have Longstrider running). This gives the golem up to four AoOs (if it has Combat Reflexes and high DEX, of course). My AC is 28. Reflex save 8+17=25 versus the sticky Web. CMB roll to then power through the Web 13+13=26. New Fort save versus the gas cloud 9+12=21.
After all that, I then shoot Student 8 in the face, using Manyshot and, should it matter, Clustered Shots.
Attack roll 11+19+4(favoured enemy)+1(PBS)=AC 32, damage 2d8+6+8(favoured enemy)+2(PBS)=25 + 8 fire + 7 electricity.
