"Wally" (if it really was Wally) took that man's hand and asked what was wrong, he also seemed scared, he just didn't give me any evil energy like people are claiming, it was just how he looked in the video, he could have tried to prevent Frank from leaving because they had a curfew and he knew what could happen if they tried to leave past that. Also we need to remember Wally really does not actually have the ability to push or do anything to anyone, we're talking about a man who can't physically push himself up when he falls, Wally was also was never jealous of Frank as people like GT says, he was simply upset that he couldn't communicate with his own house and asking the only person that could communicate with your OWN damn house was probably awkward as hell that's why in the morse code video his mannerisms looked off when asking Frank to teach him how I mean, that shit has gotta be embarrassing yo give him a break!
Bro... I'm not accusing him to be "evil" but rather I was pointing out at what he did at the moment in the video. You can literally see on tags that was written that "Wally is evil alligations are not helping-" was simply a joke that the theory of him being evil might be true. That's it.
And last thing, I don't want to go deeper in this rabbit hole, like can we not? This account is purely made for posting my art and my rambles with my own opinions and not this and I wish this is the last thing I see.
I'm sorry if my answer wasn't your cup of tea cause I try my best to give your answer as much as I can.
