Play fighting was just fine with Terrence; it wasn't like he actually wanted to hurt Katie. And it was ridiculous fun, jumping around on the boat, occasionally missing a step when the deck moved beneath him, getting squawked at by her parrot. They'd taken a brief detour into serious topics, but this was really why he'd wanted to hang out with Katie today; he'd been far too serious recently, even if he'd been playing for both teams, politically speaking.
This? This was just a good, old-fashioned, pretend sword fight. With ridiculous costumes to boot. "I'll wipe the deck with ye," he challenged, trying to back her towards the helm, his grin getting extremely mischievous. "And then make ye walk the plank, ye and yer squawky little parrot!"
