none except Mark is holding a cup that says Tom.

On April Fool's day lol. Was most likely a joke by him or whoever served him his coffee.

and Mark fully said new blink would be being worked on as early as January , he could very well be 3 months into an experimental album, and that could be why Tom until recently has been deadass quiet.

Mark did say that but it doesn't mean it happened, we as blink fans should how fast plans can change lol. And Tom's been working on TTS shit, so he of course he hasn't been as active.

Travis also has been In a studio where you can clearly see a Tom DeLonge custom 333 in it - frequently.

It's not crazy to assume Travis just has that guitar in his studio, who knows how long that's been there. Tom probably gave it to him years ago.

Mark has been working with Amy Shark - who earlier last year was talking with Tom about working together and then just all of a sudden is recording with Mark one day.

Pure coincidence. She's a blink fan so obviously she'd want to work with both of them. From what I saw on social media she and Tom never actually got together, and it seemed like Mark only visited her for the day or something.

and tagged Tom in a tweet about the ST experimental album

He tagged Tom because it was the album's anniversary and they all worked on it. It wasn't subtle foreshadowing

lets not forget about the new Travis documentary that's coming out where they're all together again- talking about blink

To be fair they don't have to be all in the same room for that, we haven't seen any footage of them together yet as far as I'm aware. All that's been said is that Mark and Tom are in the documentary.

You're reading way too deep into nothing and it's kinda sad. Instead of hopelessly looking for signs that he's coming back, just assume he isn't so that it will be even sweeter if he ever does.
