Moon Knight Multiple Personalities extra attack dice and Siege of Darkness

[Glenn]

Moon Knight activates and rolls for Multiple Personalities and gets a wild or hit, then plays Siege of Darkness.  A different Midnight Sons character makes the first attack.  Does that character get 2 extra dice on the roll?

As written it doesn’t state the next attack made by Moon Knight this activation, just the next attack this activation

[Glenn]

Also if Moon Knight moves within range two of an opposing Heimdall before he makes an attack action and Heimdall uses Forefend, does Heimdell get the extra two dice on the attack?

The benefit for Multiple personalities you are referencing will only add dice to an attack roll made by Moon Knight.

This will be made clearer in the future.
