I do not think it is that complicated.  For the traveling twin, dx' = 0 
→ dx'∕dt' = v' = 0 → gamma(v') = 1, so they do not observe time dilation in 
their frame, but only proper time; but dx' = dx/gamma(v) – length 
contraction –, so they are not amazed at all that they travel less spatial 
distance than the rest distance in less proper time.

The traveling twin can further explain that (despite what they may expect 
from the symmetry of time dilation) the home twin is older when they meet 
again, with the *relativity of simultaneity*: *by contrast* to the home 
twin, the traveling twin changes from at least one inertial frame to at 
least one other when turning around.  Assuming for simplicity that they are 
only changing from a first inertial frame to a second one when turning 
around, a different set of events in the home twin’s frame are simultaneous 
in the traveling twin’s second frame than in their first frame, and some 
home twin’s events during that journey are not simultaneous with *any* 
events in the traveling twin’s two frames (with multiple frames there is 
full correspondance, but only during the turning).  If the traveling twin 
could observe the home twin’s clock, when turning around they would observe 
that clock jumping *ahead* of their clock (with multiple frames, gradually) 
when before it was *behind* their clock.

It basically also says so in the Wikipedia article that (IIRC) I already 
referred to, among several textbooks, I am confident, and the lines of 
simultaneity in the/a Minkowski diagram clearly show it.
