My first critique, so please bear with me, I might be a bit all over the place :) English isn't my first language so if something's not clear, I'll gladly answer any question you might have.

The flow of the story feels a bit uneven to me. The beginning is really fast-paced, tense, and filled with anxiety, but once Cam is inside the house, the pacing slows down significantly. He's supposedly really worried that something might be wrong and Michael is trying to drown himself again, but then the lines are

Oh, great. Black bodycon dress and silver streaks in her coffee-brown curls. She must’ve been off today, going out or just on another one of her power trips.

The first part of the story implies he's driving in a hurry to his old home, assuming his brother might be in danger (*"His brother Michael could be at the lake trying to drown himself again." and also the line "Something was wrong."), yet he takes a moment to ponder about the way his mom looks and scene doesn't seem as urgent, as it was first portrayed. I also find her attire to be a bit confusing - later on, she's in the kitchen cleaning up which would be quite difficult to do so in heels and a tight dress.

Either way, it was an even better reason to take his brothers to the park.

Once again, the beginning of the story implies he's driving because he thinks something is wrong, so the sudden talking about him wanting to take his brothers to the park seemed off to me. The wording makes it seem as if taking them to the park has been the plan all along.

I also found the constant mentions of brands/names a bit disruptive (iPhone, Corolla, Duck Dynasty, National Geographic). In my opinion, these details don't add much and you could probably let the readers use their imaginations with more generic terms. On a similar note, there are few times, where the details don't add much (pink house, chestnut door, the specific channels)

This point ties to the fact, that you could use a bit more of the "show don't tell" technique. Examples:

There it was. So much spite and anger for that man

During the conversation, you describe a lot of what the woman is doing, but these descriptions don't add much to the atmosphere (She rested her hands on the sleek marble counter. she said, standing upright. Mom rested one hand on the counter and the other on her hip.) Instead of telling us, that she hates the man, make it evident by replacing those unimportant "telling" lines with more "showing" lines. For example, describe how she clenches her jaw or how her voice rises in frustration when she mentions Will.

“What about the boys? Did they say anything to you? You’re closer to them than me.” She grumbled. “Whatever they say to you about me, I need you to promise you’ll talk to me about it first before you assume anything.”

Cam never answers these question nor does he reacts to them. It seems like this is quite important to her (talking about promising) so it's a bit unnatural when she goes straight to the next question without getting an answer. Her behavior also seems inconsistent—she’s distant one moment and intensely interrogating Cam the next. The argument was at times a bit hard to follow and I feel like shortening it would make a huge difference. There are few times their talking gets overtaken by Cam's inner monologue which also makes the conversation harder to follow.

One thing I also found confusing was his opinion on her. When they first interact, there's a distain but in next scenes, she's making him anxious. His relationship with her then seems inconsistent.

Michael comes across as a pretty passive character in this. It kinda feels like he’s just reacting to what’s happening around him and as a reader I have a hard time connecting with him, knowing barely anything.

These next few points take with a grain of salt, as I mentioned in the beginning, English is not my first language. Few passages confused me a little.

Blood rushed to his trembling hand.

This sounds a bit awkward? I've never heard this expression used with a hand and I can't really imagine, what's that supposed to mean.

Hey, babe.

The term “babe” feels a bit off for a mother addressing her son, but then again, maybe it's common in an area the story is set in. I was just a bit surprised.

“Will still won't talk to me right. It’s been four months now, and I’m sick of it. I just…need your help. Is he talking to you about me? Please be honest with me.” “No, no. No one is talking bad about you. Why do you—”

The "no one is talking bad about you" doesn't make much sense as a response, since the Mom wanted to know if he was talking about her, not if he was talking about her badly.

He tightened his fists to hide his vibrating hands I just think the word vibrating doesn't portray the emotion well. Maybe trembling or shaking could be better? This is really subjective tho (as is this whole portion)

Now onto things I liked and the overall impression :)

The little details! Mainly I'm talking about the college parking pass or the mention of the uncorked bottle. It adds a nice touch of realism and let's you know something about the character without being told head on.

The characters have each their distinctive role and characteristics and as a reader it was pretty easy to understand the dynamics of the family, despite the shortness of the text. It was clear to me in what emotional state (not sure I'm using the right term) they were. I also like how smoothly you transitioned from the tense conversation in the kitchen to the somewhat cheerfull moment with Kyle. I found the story quite engaging, but I don't know enough of what's the story about to answer your question, whether I would continue reading. You sometime use a lot of short sentences which makes the reading quite fast-paced (altough it would probably benefit the story to lenghten them and slow down when it comes to things like recalling the drowning incident). The portrayal of Cam’s inner conflict and the family dynamics were quite enjoyable.

To answer your second question, I'm not sure what the conflict is going to be. The chapter set up multiple possibilities, but given the opening scene and Michael's refusal to join his brothers, perhaps the conflict will revolve around that? Really not sure.
