Sibling trio's telepathy ability

(Frozen Summer, Chapter 3)

‘Mitoshi, I … I see all of you, but, … to me, you were all … dead. You're all dead in front of me right now.’

Mitoshi was startled before grinning reassuringly. ‘I'm not dead, I promise! We need to find Latoshi, though! I'm not sure how to … tune this 'frequency', or whatever we're doing, to call him!’

Antoshi thought for a moment. ‘Could it be that … we're hearing each others' thoughts? Like, … telepathy?’

‘I—I guess that's possible?’ she replied, confused. ‘I didn't know we could do this!’

‘Neither did I. Why don't we … try to search him out with our minds? You were calling out to me when I heard you, let's try the same for him!’ Mitoshi nodded in response.

‘Latoshi!’ they both called out in their minds. ‘… Latoshi!’

Latoshi wept and trembled as Lazarus inched ever closer to him.

‘Latoshi!!’ he heard the voices of his siblings in his head. He gasped loudly.

‘An … toshi?’ he thought, finally recalling his brother's name. ‘… Mitoshi?’ His inner voice got through the two, who were equally ecstatic to hear him.

‘Latoshi!’ Antoshi spoke to him. ‘Are you all right? Where are you right now?’

Latoshi held his head, trembling in disbelief. ‘Antoshi? Is that really you?’
