the choice to have loki initiate the hug, to initiate a hug at all, is absolutely reeling in my mind
if mobius had reached for the hug, it would've been an easier choice for loki to just comply to it
with mobius actually just reaching out his hand, it would've been easier for loki to comply to that, to choose not to be vulnerable and shake mobius' hand like he's inviting him to
but mobius reached out his hand for a handshake. and loki went out of his way to hug him anyway.
loki wanted to hug mobius. and by god did he do it.
