With the Web-Warriors evicted from their Earth-001 HQ by the Electros and separated in different universes, Spider-UK issues a challenge through the Web of Life to call out the Dillons and their expies to a showdown on Earth-803 (Lady Spider's world). This is a delaying tactic for Spider-Gwen, Spider-Uncle Ben and their ally Octavia Otto on Earth-983 to re-infiltrate the Electro-Warriors' base in Earth-449 to confront their eldritch leader, Battery!Electro. Octavia's plan to wipe Battery's collective minds with a teleconsciousness helmet (ooh, remember this, SpOck-critics?) fizzles out, so Gwen teleports her group and Battery to Karn's (and the others') location. The Web-Warriors encase the Electros with Pavitr's special conductive (and apparently permanent) webbing cage to neutralize and trap them, but Karn is slowed by hunger to clear the web's general area. Spider-UK lets Karn drain him to give him enough strength to be dragged out by Spider-Gwen, but Mayday drops into the cage to rescue the depleted UK. With little time before the Elcetros wise up to their plan, Anya - as UK's second in command - orders the others to completely seal the cage. Karn assures the other Warriors that UK and Mayday have used their damaged teleport watches to escape, but is unsure what universe them may have gone out due to the Electros damaging the Web of Life back in 001. Uncle Ben takes his leave to look after his adopted universe and family in the absence of Mayday, while the other Warriors can only hope to locate their missing two any other time than now. As Karn says, the Web needs all of them.
Wow, way to throw Mayday under the bus again. That fact that the letters page crew act as if Billy Braddock/SpUK and Mayday were KIA like they "promised" in the #5 preview solicit was just grating. And no hint on the next ish teaser what will happen on #6. Bad form.
