Yes, they kissed in Time Paradox.

'Holly,' he said, when his vision cleared. His smile was sincere and grateful. 'You saved me again.'
ہولی was laughing and crying at the same time, tears spilling on to Artemis's chest.
'Of course I saved you,' she said. 'I couldn't do without you.' And because she was happy and flushed with magic
ہولی leaned down and kissed Artemis, magic sparking around the contact like tiny fireworks.

Then, Later...

He was instantly alert. ہولی had kissed him. Artemis back-pedalled, jumping to his feet, spreading his arms
wide to counteract the sudden dizziness.
'Eh, thanks,' he کہا awkwardly. 'That was unexpected.'
ہولی smiled, feeling a little embarrassed. 'Artemis, you're OK. Any مزید healings and you'll be nothing but
scar tissue held together سے طرف کی magic thread.'
