Shepard can't help a bit of a smirk as she looks up at her friend continuously deny needing help.

"Oh of course you can. Any time you want. You'll probably decide to come down soon, right?"

She flexes her arms a bit, showing off her biceps for fun. It's been awhile since she felt this playful but there's something about Lup that brings it out in her again. Lights a flame in her heart, if you will, from a fire she thought long dead.

"When you do, I'll be here. Though... since you're so sure of your position up there, you wouldn't mind me touching this tree at all, would you?"

Her smirk grows as she gently touches the tree. She's not shaking it. Yet.
