- ↑ page 474 of Neverseen: "Keefe let out a sigh that sounded more like a groan. 'And I thought secret Telepath conversations were the worst. Just so we’re clear,' he told Tam. 'I’m the president of the Foster fan club. And we’re closed to new members.' // Tam’s cheeks flushed. “Uh . . . not sure what that’s about but . . . no worries there—no offense!' he told Sophie.// She noticed he stole a quick glance at Biana after he said it."
- ↑ page 284 of Lodestar: "'[...] Plus, I haven't seen you in forever.' // Tam's lips twisted into a shy smile. "I hear we'll be seeing more of each other soon."
- ↑ page 284 of Lodestar: "Sophie and Fitz hurried to follow, but Dex stayed put. She figured that meant he wanted to stay with Biana and Tam, but as they reached the arched bridge connecting the two tree houses, Dex came racing up."
- ↑ page 407 of Lodestar: "'She's not his type,' Linh jumped in. 'He likes brunettes.' // 'Gross, why do you know that?' Tam asked. // Linh smirked. 'Because you're not as sly as you think.'"
- ↑ page 407 of Lodestar: "'And she's not staring at us,' Biana corrected. 'She's checking out Tam.' // Tam's eyebrows shot up, and he stole another glance. Marella tossed her long blonde hair-- which always had a few tiny braids woven in-- and gave him her flirtiest smile. // 'Huh,' he said. // 'That's all you have to say?' Biana pressed."
- ↑ page 547 of Lodestar: "'While someone was getting their beauty sleep, I went to the Silver Tower with Tam to see if having a Vanisher with him made a difference. And we finally figured out how the Neverseen got in!"
- ↑ page 549 of Lodestar: "'How does it give the Neverseen access to the tower?" // 'Because they brought a Shade,' Biana said, nudging Tam forward. 'Go on. Show them how cool you are.' // Tam flushed, squaring his shoulders as he approached the glass."
- ↑ page 583, 584 of Lodestar: "'We're setting up a secure residence for them here in the Lost Cities. That way they'll no longer feel so isolated. Blur has offered to serve as their guardian, and the Council will be assigning them goblin bodyguards. And they've been granted permission to attend Foxfire, once the term resumes again.'"
