During the first half of the Liberty Island fight scene (Cyclops, Storm, Jean Grey & Wolverine vs Toad & Mystique), Wolverine is separated from the group by Mystique and Toad attacks the others by locking Cyclops in a display case, tossing Storm onto an overhead balcony, and spitting suffocating slime on Jean.
However, after seeing Storm watching him and Jean, he leaps to the balcony and smiles at her before kicking her all over the place, finally locking her in an empty elevator shaft. Why? If he had used the slime he had used on Jean Grey, wouldn't she have been just as helpless?
After all, he could easily prevent any of the other X-Men reaching her before she ran out of air. Not to mention, she could easily fall into the open elevator shaft or over the edge of the balcony and break her neck. Any thoughts would be appreciated.
