Q: Boston (CNN)She knew something awful had happened. It was smoky and all she could hear were muffled screams. Her foot was turned sideways and her legs wouldn't work right. And her good friend, Krystle Campbell, was just lying there on the ground.

Karen Rand -- she's Karen McWatters now -- dragged herself across the pavement. She wanted to get closer to Krystle so they could talk and take comfort from each other in the midst of so much chaos.

"I got close to her, " she recalled. "For some reason, I got close to her head and we put our faces together."

Krystle said that her legs hurt. They were the last words she'd speak. The two women held hands until Krystle's went limp.

McWatters was the fifth witness of the first day of the terror trial of accused Boston Marathon bomber Dzhokhar Tsarnaev, who is accused of detonating pressure cooker bombs with his brother to punish the United States for policies they believe inflict suffering on Muslims.

Three people were killed in the blasts: Campbell, a 29-year-old manager for a restaurant chain; Martin Richard, an 8-year-old boy; and Lingzi Lu, a 23-year-old grad student.

More than 250 others were injured. And the first day of the trial -- after opening statements -- revolved around a number of survivors of the attack, who recounted in detail the chaos of that day. Prosecutors called them to the stand to paint a picture of the havoc and pain the bombings inflicted. Tsarnaev's attorneys chose not to cross-examine any of the survivors.

Q: A Texas teen who's been jailed more than four months for a Facebook comment he made during a video-game argument is finally getting a day in court that could let him go home.

Justin Carter, who was 18 when he was arrested, will appear in Comal County (Texas) District Court on Tuesday, July 16, for a bond hearing, according to his lawyer, Don Flanary.

Flanary told CNN he will argue to have Carter's $500,000 bond, which his family cannot afford to cover, reduced.

Flanary, who is working the case for free, met with Carter for the first time on Tuesday. He said Carter is not doing well, and his family says he has been placed on suicide watch.

"Justin is in bad shape and has suffered quite a bit of abuse while in jail," Flanary said in an e-mail. "We will likely bring out these issues at the bond hearing."

He did not elaborate on the type of abuse claimed by Carter, who is now 19.

In February, Carter and a friend were arguing on Facebook with someone else over the online video game "League of Legends."

His father told CNN that the other gamer called Justin crazy and his son responded with sarcasm.

According to court documents, Justin wrote, "I'm f***ed in the head alright. I think I'ma (sic) shoot up a kindergarten and watch the blood of the innocent rain down and eat the beating heart of one of them."

Jack Carter said his son followed the claim with "LOL" and "J/K" -- indicating that the comment wasn't serious.

Q: Washington (CNN) -- When Paul Ryan struggled to explain a budget-balancing timeline under Mitt Romney, he highlighted the difficulty of trying to run a substantive campaign without being too specific.

While Ryan's interview Tuesday with Fox News' Brit Hume was no Sarah Palin-Katie Couric moment, the Republican vice presidential candidate's discomfort in answering when Romney's proposal would balance the budget was evident.

Ryan, a seven-term congressman from Wisconsin and chairman of the House Budget Committee, said he was unsure when Romney's proposals would balance the federal budget. Romney's plans say he would "put the federal government on a course toward a balanced budget" but does not say when.

Mitt Romney's 5-point plan for the economy

Hume repeatedly pressed Ryan on the question of "when" Romney's budget would balance.

Hume: "The budget plan you're now supporting would get to balance when?"

Ryan: "Well, there are different -- the budget plan that Mitt Romney is supporting gets us down to 20% of GDP (gross domestic product) government spending by 2016. That means get the size of government back to where it historically has been. What President Obama has done is he brought the size of government to as high as it hasn't been since World War II. We want to reduce the size of government to have more economic freedom."

Hume: "I get that. What about balance?"

Ryan: "I don't know exactly what the balance is. I don't want to get wonky on you, but we haven't run the numbers on that specific plan. The plan we offer in the House balances the budget. I'd put a contrast. President Obama, never once, ever, has offered a plan to ever balance the budget. The United States Senate, they haven't even balanced, they haven't passed a budget in three years."
